Question

Identify false statement regarding $\sigma$ and $\pi$ bonds.

• A. In $\sigma$ bond electron cloud is distributed in a cylindrically symmetrical way around the axis
• B. In $\pi$ bond electron cloud is distributed in above and below the axis
• C. Strength of $\sigma$ bond is greater than $\pi$i bond
• D. s-orbitals can form $\pi$ bond

Answer 1

Answer: (D)

s-orbitals can form $\pi$ bond

σσ bond, is basically a covalent bond formed due to the overlap of atomic orbitals along the inter-nuclear axis.

ππ bond is formed due to the lateral overlapping of the atomic orbitals perpendicular to the internuclear plane. So, now if you take the spherical s-orbital and form a bond(only one bond is formed between two orbitals) since it is symmetric( from all perspective),any bond formed will lie along the inter-nuclear plane( more precisely axis), therefore it will always be σσ bond.
