Number of σ and π- bonds in acetylene is

Options

(a) 2σ and 3π
(b) 3σ and 2π
(c) 3σ and 3π
(d) 2σ and 2π

Correct Answer:

3σ and 2π

Explanation:

In acetylene, σ-bond is formed by the sp-hybrid orbital of carbon and one s-orbital of hydrogen at an angle of 180⁰ as well as two unhybridised p-orbitals at each carbon atom forms 2 π-bonds by parallel overlap.Thus acetylene contains. 3σ and 2π bonds.
