the boiling point of ethyl alcohol is much higher than that of dimethyl ether through both have the same molecular weight why a. ether is insoluble in water b. methyl group are attached to oxygen in ether c. dipole moment of ethyl alcohol is less​

Answer:

orrect option is

C

hydrogen bonding

Hydrogen bonding increase the boiling point as here required separation energy is more. In case of ethanol OH is the last so one hydrogen is attached with a very electronegative atom (oxygen) directly. So both oxygen and hydrogen become polar. So hydrogen bonding is possible here, which increase the boiling point of ethanol. In case of dimethyl ether oxygen is not directly attached with the hydrogen so hydrogen bonding is not possible so its boiling point is less than ethanol.

So option C is the correct answer.
