Statement – I : Boiling points of carbonyl compounds is lesser than boiling point of corresponding alcoholsStatement – II : Dipole – dipole attractions is weaker than intermolecular H - bonding

Intermolecular attractions in alocohols  is H-boning.Intermolecular attactions in carbonyl compounds are dipole-dipole attractions.Ketones are more polar than aldehydes. Inter molecular attractions in ethers are weak dipole -dipole attractions.
