    The boiling point of \[{{C}_{2}}{{H}_{5}}OH\] is much higher than that of dimethyl ether, though both have the same molecular weight The reason for this is:

    A)  Dipole moment of \[{{C}_{2}}{{H}_{5}}OH\]is less

    B)  Ether is insoluble in water

    C)  \[{{C}_{2}}{{H}_{5}}OH\]Shows hydrogen bonding

    D)  Methyl group are attached to oxygen in ether

    Correct Answer: C

    Solution :

    Due to hydrogen bond the boiling point of ethyl alcohol is higher than dimethyl ether. Dimethyl ether is not capable to form H - bond.
