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.
 

	List - I		List - II
P)		1)	p-d π antibonding
Q)		2)	d-d $\sigma$ bonding
R)		3)	p - d π bonding
S)		4)	d - d $\sigma$ bonding

The correct match is
 

	P	Q	R	S
1)	2	1	3	4
2)	4	3	1	2
3)	2	3	1	4
4)	4	1	3	2

P  is overlaping of two orbitals of d_x²−y² and is bonding=d-d σ bonding-2

Q is overlap of p_y and d_xy, thus its π overlap and is bonding-p-d π bonding-3

R is overlap of p_y and d_xy, thus its π overlap and is antibonding p-d π bonding-1

S is overlap of d_z² and d_x²−y², thus its σ overlap and is anti-bonding-d-d σ bonding-4

P−2, Q−3, R−1, S−4
