1 Orbital, Shae and Polarity Quiz Name: /17 Knowledge. Anwer the following quetion on foolca. /2 1. Exlain why the ub-level can aear to be herical like the ub-level? /2 2.a) What i the maximum number of i bond that a ub-level can form? Exlain. /2 b) A bond form between a 2 hybridized orbital from one atom and a 2 hybridized orbital from another atom. I thi bond likely to be a igma or i bond? Exlain your reaoning. /7. With the aid of diagram, redict the mot table hae of a 2 SO molecule. /2 4. Arrange the following molecule/ion in order of decreaing angle between the marked (curved line) bonded atom? /2 5. Exlain what effect loing 1 electron from N in N would have on it hae. /20 Communication. Anwer the following quetion on foolca. /2 6. Draw the orbital diagram to rereent 4. /5 7.a) Draw orbital diagram to how the bonding in the mot table redicted NC 2 molecule. /5 b) Label each bond and orbital in your diagram. /8 8. For each of the following combination of molecule: i) IO ii) XeOF 4 (Xe electronegativity = 2.6) a) draw and name the geometric hae of the molecule. b) illutrate the bond olarity and tate whether or not the molecule i olar.

2 Orbital, Shae and Polarity Quiz Name: /17 Knowledge. Anwer the following quetion on foolca. /2 1. Exlain why the ub-level can aear to be herical like the ub-level? electron motly found at the ti of the orbital but the orbital are contantly moving around the nucleu creating the aearance of herical hae (like a inning triangle look like a here) /2 2.a) What i the maximum number of i bond that a ub-level can form? Exlain. 2 there are orbital and 1 mut form a igma bond to allow any i bonding leaving only the remaining 2 available for i bonding /2 b) A bond form between a 2 hybridized orbital from one atom and a 2 hybridized orbital from another atom. I thi bond likely to be a igma or i bond? Exlain your reaoning. igma bond becaue a i bond involving ideway overlaing and the bond forming between 2 orbital contrain the hared electron into the one ignificant 2 lobe from each atom would require too much energy comared to the direct overla of the igma bond that could form /7. With the aid of diagram, redict the mot table hae of a 2 SO molecule. O S ulfur could ingle bond to an and the O and then the other could ingle bond to the O (recall eaily bond to very electronegative atom) thi create a line of bent hae a the S and O both have 4 electron air with 2 bonding air and 2 non-bonding air each from left to right F.C: S: = 0 O: = 0 OR work ince there i no electron ditribution iue in that there are no atom with formal charge and all atom have table electron configuration O S ulfur could ingle bond to the atom and then hybridize a air of electron, ingle bond to the O and then reditribute the lone remaining electron to the O create a trigonal yramid hae (reult in 4 electron air around S, igma bond and 1 lone-air) from to to bottom F.C: O: = -1 S: = 1 OR even though all atom have table electron configuration, thi i not a likely due to an electron deficit on S and electron loading on O

3 O S ulfur ingle bond to the atom and then hybridize a air of electron and double bond to the O thi create a trigonal yramid hae (5 electron around S with igma bond, 1 lone air and 1 i bond the igma and 1 lone air create a tetrahedral hae (4,1), but only air are actual bond) from to to bottom F.C: O: = 0 S: = 0 work ince there i no electron ditribution iue and all atom have table electron configuration (well ort of, the i bond ull one air of electron further away from the other 4 air making them le reulive than if there were jut 5 air of electron in igma oition meaning ulfur can tolerate 10 outer electron) o you would not likely redict thi one a being a table oibility but if told it did work, you could now exlain it o, in the end, two oible configuration but you would ick the firt one a being mot table /2 4. Arrange the following molecule/ion in order of decreaing angle between the marked (curved line) bonded atom? b, a, c in b, reulion on bonding air but the F draw it hared electron air away from P o the reulion between F-Cl atom i le allowing the reulion between the Cl to be felt more and they uh away from each other creating an angle bigger than 120 in a, all the reulion are equal and the angle i 120 in c, the lone air of electron are mot reulive ince they are very cloe to P making the lone air- Cl reulion ignificant uhing the Cl atom together making the angle le than 120 /2 5. Exlain what effect loing 1 electron from N in N would have on it hae. there will be a lone electron on N which mean it will be le reulive than when there wa a air of electron thu, the angle between the atom will relax omewhat and become lightly larger, but not a in the tetrahedral

4 /20 Communication. Anwer the following quetion on foolca. /2 6. Draw the orbital diagram to rereent 4. all look the ame and you mut draw all orbital (full and emty) /5 7.a) Draw orbital diagram to how the bonding in the mot table redicted NC 2 molecule. /5 b) Label each bond and orbital in your diagram hae, alignment, labelling and filling are very ecific notice full of N and C not included ince they do not bond notice lobe only labelled once becaue they are comlete a a bi-lobe notice bonded lobe have ooite facing electron note i bond labelled once but dahed line curve inward to both lobe /8 8. For each of the following combination of molecule: i) IO ii) XeOF 4 (Xe electronegativity = 2.6) a) draw and name the geometric hae of the molecule. b) illutrate the bond olarity and tate whether or not the molecule i olar. i) IO oibilitie: I hybridize twice, all O atom ingle bond with electron hifting from I to O but F.C. oor I hybridize twice, one O atom double bond and two O atom ingle bond with an electron hifting from I to one of the O atom but F.C. oor I hybridize twice, two O atom double bond and the other O atom ingle bond and F.C. i bet o I ha 6 electron air, but only igma and one non-bonding air o I ha an architecture of (4,1) trigonal yramidal vector create a net olarity o the molecule i olar notice wedge drawing i very ecific (bold olid triangle = coming outward o get larger moving outward while hahed triangle i not olid and get maller a it fade backward)

5 ii) XeOF 4 2 oibilitie Xe hybridize three time, all atom ingle bond and twice, with an electron hifting from Xe to the O but F.C. oor Xe hybridize three time, all F atom ingle bond and O atom double bond F.C. i bet Xe ha 7 electron air, but only 5 igma and 1 non-bonding air o Xe ha an architecture of (6,1) quare yramidal vector create a net olarity o the molecule i olar (F ha more ull and unymmetrical hae) utting O i unlikely ince it i much more electronegative than Xe attaching a F to O i oible but then the hae would not have a name o it i imlied that a better, more likely anwer hould be ued note that there i often more than one way to do thee and ometime thi create different anwer the mot table verion i the mot likely, but thi wa not art of the quetion (o you don t actually have to do all the F.C. work jut ick one and go from there) Preared by K.
