Electronegativity order: $sp^3 > sp$ (for carbon atom)

Vedclass · Answer

(D) $1$. Ionisation potential $(IP)$ decreases down the group. Thus,$IP$ of $Cl^{-}  Cl^{-}$. However,comparing the options,let us evaluate $D$.$2$. Electronegativity depends on the percentage of $s$-character. $s$-character in $sp^3$ is $25\%$,while in $sp$ it is $50\%$. Therefore,electronegativity order is $sp > sp^2 > sp^3$. The statement $sp^3 > sp$ is definitely incorrect.$3$. $F $4$. $O^{-} < S^{-}$ is correct for $IP$ as $S$ is larger than $O$.
