हिन्दीIn the excited state of phosphorus (\( Z = 15 \)) during the formation of \( \text{PCl}_5 \), calculate the number of unpaired electrons available for hybridization.
Correct answer · Option 3
5
Explanation
In the excited state, one 3s electron is promoted to 3d, giving configuration 3s¹ 3p_x¹ 3p_y¹ 3p_z¹ 3d¹, resulting in 5 unpaired electrons.
