Both $(a)$ and $(c)$

Vedclass · Answer

(D) For option $(a)$: The electron gain enthalpy becomes more negative as we move from $I$ to $Cl$. However,$F$ has a lower electron gain enthalpy than $Cl$ due to its small size and inter-electronic repulsion. The correct order is $I For option $(b)$: Metallic radius increases down the group as the number of shells increases. The order $Li For option $(c)$: Ionisation enthalpy generally increases across a period. However,$N$ has a stable half-filled $2p^3$ configuration,making its ionisation enthalpy higher than $O$. The correct order is $B Since both $(a)$ and $(c)$ do not agree with the indicated property,the correct option is $(d)$.

In which of the following options the order of arrangement does not agree with the variation of property indicated against it?
