(D) D < A < B < C

Step-by-step Solution

Detailed explanation

\(\mathrm{N}:-1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^3\) (વિદ્યુતઋણતા \(\left.=3\right)\) \(\mathrm{O}:-1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^4\) (વિદ્યુતઋણતા \(=3.5\)) \(\mathrm{F}:-1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^5\) (વિદ્યુતઋણતા \(=4\))…
