Question

Which of the following statements is incorrect ?

A. $$N{H_3}$$  is more basic than $$P{H_3}.$$
B. $$N{H_3}$$  has a higher boiling point than that of $$HF.$$  
C. $${N_2}$$  is less reactive than $${P_4}.$$
D. The dipole moment of $$N{H_3}$$  is less than that of $$S{O_2}.$$
Answer :   $$N{H_3}$$  has a higher boiling point than that of $$HF.$$
Solution :
Due to high $$EN$$  of $$F$$ than $$N, H$$  - bonding is stronger in $$HF$$  than $$N{H_3}$$  thus $$b.pt.$$  of $$HF > N{H_3}.$$
