$C  P > N$ : Electron gain enthalpy

Vedclass · Answer

(C) $1$. Non-metallic character increases across a period and decreases down a group. The order $F > N > C > Si > Ga$ is correct as $F$ is the most non-metallic.$2$. Oxidizing power is related to electronegativity and electron gain enthalpy. The order $F > O > Cl > N$ is generally accepted for oxidizing power,but $F > Cl > O > N$ is often cited in specific contexts. However,let's check the electron gain enthalpy.$3$. Electron gain enthalpy (magnitude) generally increases across a period and decreases down a group. The order for electron gain enthalpy is $Cl > F > S > P > O > N > C > Si$. The given order $C  P > N$ is incorrect because $Si$ does not have a higher electron gain enthalpy than $P$ or $N$ in the standard periodic trend.
