Which is expected to have highest melting point: PH_3 , NH_3 , (CH_3)_3,N? Explain.

Answer»

Solution :`NH_(3)` has the strongest intermolecular hydrogen bonding and it is expected to have the heighest melting point. Acutal melting points are: `NH_(3)=-77.7^(@)C,PH_(3)=-133^(2)C` and `(CH_(3))_(3)N=-117^(@)C`.
