$In oxygen and carbon molecule the bonding is$

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $O_{2} : 1 σ, 1 π; C_{2} : 0 σ, 2 π$
B $O_{2} : 0 σ, 2 π; C_{2} : 2 σ, 0 π$
C $O_{2} : 1 σ, 1 π; C_{2} : 1 σ, 1 π$
D $O_{2} : 2 σ, 0 π; C_{2} : 0 σ, 2 π$

Correct answer: A

Solution

(a): O_{2} has 1 σ and 1 π bond but C_{2} molecule has 2 π bonds.
