Question

Match the orbital overlap figures shown in List-I with the description given in List-II and select the correct answer using the code given below the lists

Column I		Column II
P		1	$p-d\pi$ antibonding
Q		2	$d-d\sigma$ bonding
R		3	$p-d\pi$ bonding
S		4	$d-d\sigma$ antibonding

• A. (P) - (2), (Q) - (1), (R) - (3), (S) - (4)
• B. (P) - (4), (Q) - (3), (R) - (1), (S) - (2)
• C. (P) - (2), (Q) - (3), (R) - (1), (S) - (4)
• D. (P) - (4), (Q) - (1), (R) - (3), (S) - (2)

Answer 1

Answer: (C)

show axial overlapping in same phase. So, it is $d-d\sigma$ bonding.

overlapping in same phase. So, it is $p-d\pi$ bonding.

opposite phase, so, it is $p-d\pi$ antibonding.

axial overlapping in opposite phase. So, it is $d-d\sigma$ antibonding.
