Both hexane and `CF_(4)` have the same molecular mass and are non-polar, yet the boiling point of hexane (341 K) is greater than `CF_(4)` (144 K). Why ?

Text Solution

Verified by Experts

Hexane is a straight-chain alkane (or underanched), so it is less compact or has more surface area and hence has higher boiling point than `CF_(4)`. Whereas, `CF_(4)` is spherical and has less approachable area for intermolecular attractive force and has lower boiling point.

Explain why alcohols and ethers of comparable molecular mass have different boiling points?

In general boiling point of covalent compounds is affect due to increasing molecular weight and hydrogen bonding. Thus it is obversed that the boiling point of octanol is greater that water while that of methanol is lesser than water. The other properties which are considerably affected due to hydrogen bond formation are acidic nature, melting point, anamalous behaviour of water below 4^(@)C ., It is therefore concluded that hydrogen bonding palys a vutal role in explaning many observable facts.
