Lking at the mlecules in three dimensins (belw), nepentane lks mre spherical. A sphere has a minimum surface area. The Lndn frces n these nnplar mlecules perate at the surface. Mre surface area (n-pentane) means mre Lndn frces. Mre Lndn frces means higher biling pint.
2 b. Ethanl can -bnd (-). Dimethyl ether is plar, but -bnding is strnger. c. F can -bnd. d. Lil is inic, in-in frces are the largest. e. n-pentane has mre surface area and mre electrns s its Lndn frces are greater than n-prpane. f. Dimethyl ether is plar; diple-diple frces strnger than Lndn. 36. a. All are nnplar with the same shape (fr example). Lndn frces are the dminate. The depend n the number f electrns. Br 4 has 146, cmpared with 42 in F 4 and 74 in l 4. Br 4 is the highest biling pint. b. LiF is inic, l 2 is nnplar and Br is plar. The Lndn frces f l 2 are the weakest, giving it the lwest freezing pint. c. 3 3 is plar, 3 2 can -bnd and is nnplar. The -bnd in 3 2 is the strngest making it mre difficult fr the mlecules t g int the vapr phase. d. F and 2 2 can -bnd. 2 S is just plar. 2 2 can -bnd thrugh mre X- bnds, therefre the -bnd is strngest in 2 2. Intermlecular frces resist flw, s 2 2 is the mst viscus. e. 2 is plar, 3 3 and 4 are nnplar, with 4 having fewer electrns. eat f vaprizatin ges alng with strength f intermlecular frces. 2 has diple-diple frces, s it wuld have the greatest heat f vaprizatin. f. I 2 is nnplar, sbr and a are inic, but the lattice energy in a is greater (2+, 2- ins, versus 1+, 1- ins). I 2 is the weakest intermlecular frce; easiest t melt; smallest enthalpy f fusin.
