Question

Which of the following is correct incase of overlapping of orbitals ?
S - S > S - P > P - P
S - P > S - S > P - P
S - S < S - P < P - P
P - P > S - S > S - P​

Answer 1

Answer:

p−p>s−p>s−s

Explanation:

On the basis of extent of overlapping, greater the area of overlapping greater is the strength of bond. Since the area of overlapping is greatest in case of p−p bond due to its dumbbell shape followed by s−p & then s−s.

Hence bond strength decreases in the order.
