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

Question

The electronegativities of N, C, Si and P are in the order (A) P < Si < C < N (B) Si < P < N < C (C) Si < P < C < N (D) P < Si < N < C

Electronegativity increases on moving left to right in a period and decreases for the period below it

(∵ n =

increases

)

∵ (N

and

C)

and

(S i

and

P)

respectively belongs to

(n = 2)

and

(n = 3)

∴

Electronegativity of

N >

electronegativity of

C

and electronegativity of

P >

electronegativity of

S i

Hence, correct order is:

S i < P < C < N
