Q20 / 75 · JEE Main 2025 (22 Jan Shift 2) · Chemistry
The maximum covalency of a non-metallic group 15 element ' E ' with weakest $\mathrm{E}-\mathrm{E}$ bond is :
- Correct answerA4
- B6
- C3
- D5
Solution
$\mathrm{N}-\mathrm{N} < \mathrm{P}-\mathrm{P}$ : single $(\sigma)$ bond strength
Due to L.P.-L.P. replusion
and maximum possible covalency of nitrogen is 4 .
Hence, the correct answer is option: 'A'.
