In general,the lower the ionisation energy,the higher the reducing property (in gas phase).

Vedclass · Answer

(C, D) Statement $A$ is incorrect: Electronegativity and ionisation energy are both measures of how strongly an atom holds onto its electrons; they generally increase together across a period.Statement $B$ is incorrect: Metallic character is the tendency to lose electrons,which is inversely proportional to electronegativity.Statement $C$ is correct: Lower ionisation energy means an atom loses electrons more easily,making it a better reducing agent.Statement $D$ is correct: The electron affinity of $Cl$ $(349 \ kJ/mol)$ is higher than $S$ $(200 \ kJ/mol)$ and $Se$ $(195 \ kJ/mol)$. The order $Se  S < Cl$ as written in the option.
