Question:

$\text{The correct order among the following options is:}$

Options:

1. $\text{F} > \text{N} > \text{C} > \text{Si} > \text{Ga - Non-metallic character.}$
2. $\text{F} > \text{Cl} > \text{O} > \text{N - Oxidising property.}$
3. $\text{C} < \text{Si} > \text{P} > \text{N - Electron affinity value.}$
4. $\text{All of the above.}$ (Correct)

Solution:

$\text{HINT: Non-metallic character} \propto \text{Electronegativity}$\n\n$\text{Explanation:}$\n\n$\text{(1) As electronegativity increases the non-metallic character increases as tendency to form anion increases.}$\n\n$\text{(2) It is based on their SRP values. (Oxidising power may be cumulative effect of hydration energies, electronegativities, bond dissociation energies and electron gain enthalpies)}$\n\n$\text{The correct order of oxidising property is : F>Cl>O>N}$\n\n$\text{SRP , F2 = 2.87, Cl2 = 1.36 , O2 = 1.23 ,}$\n\n$\text{(3) C =-121; Si = -135; P =-60; N = +31 (all values are in KJ/mole). It depends on various factors like size of atom, nuclear charge, partially filled, half filled and completely filled electronic configurations.}$\n\n$\text{So, all are correct.}$
