- (A), (B), (D) only
- (A), (C), (E) only
- (B), (D), (E) only
- (D) and (E) only
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
• Statement (D): The stability of the +5 oxidation state decreases down the group due to the inert pair effect.
• Statement (E): Nitrogen belongs to the second period and cannot expand its octet, hence it cannot show a maximum covalency of 6.
Corrected Statements: - +5 oxidation state stability decreases down the group. - Nitrogen shows a maximum covalency of 4.
