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

Options

A. `P lt Si lt C lt N`
B. `Si lt P lt N ltC`
C. `Si lt P lt C lt N`
D. `P lt Si lt N lt C`

Answer

C

Explanation

Electronegativity increases as we more left to right in a period and decreases as we move down in the group.
(i) C and N belong to the same period. Hence N has more electronegativity than carbon (C).
(ii) In the same way P is more electronegative than Si..
(iii) As Si is below the carbon is 14th group the electronegativity of carbons is more than of Si.
