a) CH3CH2CH2CH2CH3

b) C(CH3)4

c) CH3CH2OCH2CH3

I think the first two are van dar waal (or should I call them covalent?) and the third one is dipole dipole.

a has higher BP than b because it has less branches.

But I am not sure which has higher BP between van dar wall and dipole dipole.

 

[iwannabadentist]

C > a > b

 

[potbelly]

C > a > b

agree

Just compare the molecular weights. A=72 While C =74 the one that is heavier will require more energy to leave the liquid phase and enter the gas phase.

hexane 69; ether 35; neopentane 10.

hexane 69(its pentane) bp 36; ether 35; neopentane 10.

1 degree😱. I wudnt expect something as ludicrous as that.

Counting is a bit of a challenge what with all those hydrogens in the way.
