that is ethanol,in which extent of inter-molecular hydrogen bonding with water molecules will be highest due to the presence of polar (-OH) group.Where as (
) group is less polar than that of the (-OH) group.
that is methyl amine in which extent of hydrogen bonding will higher than than that of the
that is ethanal. This is due to presence of two hydrogen atoms in primary amine which are available for inter-molecular hydrogen bonding with water molecules.
