Vedclass · Answer

(C) Electronegativity generally increases across a period from left to right and decreases down a group from top to bottom.In the periodic table,$C$ and $N$ belong to the $2^{nd}$ period,while $Si$ and $P$ belong to the $3^{rd}$ period.Comparing the values: $Si$ $(1.90)$ Thus,the correct increasing order of electronegativity is $Si < P < C < N$.

The electronegativities of $C, N, Si$ and $P$ are in the order of
