The order of bond strength of $\sigma$ bond will be $1s-1s > 1s-2p_x > 2p_x-2p_x$.

Vedclass · Answer

(D) Incorrect: The dipole moment of $p$-dichlorobenzene and $p$-dicyanobenzene is zero,but for hydroquinone ($p$-dihydroxybenzene),the dipole moment is not zero due to the orientation of the $-OH$ groups.$(B)$ Incorrect: Bond energy decreases down the group as the size of the halogen atom increases. Thus,$HI$ has the least bond energy.$(C)$ Incorrect: In $NaHCO_3$,$HCO_3^-$ ions are linked by intermolecular hydrogen bonding.$(D)$ Correct: The strength of a $\sigma$ bond depends on the extent of overlap. The $1s-1s$ overlap is the strongest due to the small size of the $1s$ orbital,followed by $1s-2p_x$,and $2p_x-2p_x$ is the weakest among these.
