JEE Advanced 2018 Chemistry question

Based on the compounds of group 15 elements, the correct statement(s) is (are)

(A) is more basic than Correct
(B) is more covalent than Correct
(C) boils at lower temperature than Correct
(D)The N−N single bond is stronger than the P−P single bond

Answer: (A),(B),(C)

Solution

(A) Metallic character, and hence basicity of oxides, increases down the group: is more basic than the strongly acidic : true. (B) N is small and highly electronegative, so the N-F bonds in are covalent, whereas the large, electropositive
