Question

(D) All the statements except $(d)$ are correct.$\sigma$-bonds are formed by head-on overlap of orbitals,making them stronger than $\pi$-bonds formed

Vedclass · Accepted Answer

$\sigma$-electrons are referred to as mobile electrons

Vedclass · Answer

(D) All the statements except $(d)$ are correct.$\sigma$-bonds are formed by head-on overlap of orbitals,making them stronger than $\pi$-bonds formed by lateral overlap.Hydrogen bonding is a strong dipole-dipole interaction,which is stronger than weak dispersion forces (London forces).Ionic bonding is electrostatic in nature and is non-directional.The statement in $(d)$ is incorrect because $\pi$-electrons,which are loosely held in the $\pi$-molecular orbital,are referred to as mobile electrons,not $\sigma$-electrons.
