Question

between alkyl halides and ether which has higher boiling point

Answer 1

The alkyl halides and ether are comparable in polarity so they can be differentiated on basis of Van der waal forces which depends on molecular mass. With the same number of carbon chain alkyl halide having higher molecular mass than ether hence little bit more polar than ethers and having higher boiling point. Moreover there are 3 lone pairs of electron in haloalkane as compared to 2 lone pairs in ether.Ether are symmetric in the sense alkyl chain in both side of electronegative oxygen.All these factor makes ether less polar than alkyl halides hence lower boiling point.
