Vedclass · Answer

(B) Statement $A$ is incorrect because the electron gain enthalpy of $Cl$ is more negative than that of $F$ due to the small size and interelectronic repulsion in $F$.Statement $B$ is correct because ionization enthalpy generally decreases down a group due to an increase in atomic size and shielding effect.Statement $C$ is incorrect because electronegativity is a property of an atom in a molecule and it depends on the hybridization and the nature of the atoms bonded to it.Statement $D$ is incorrect because $Al_2O_3$ is amphoteric,but $NO$ is a neutral oxide.Therefore,statements $A, C,$ and $D$ are incorrect.
