The electronegativity of the following elements increases in the order.

The electronegativity of the following elements increases in the order

Options

(a) C, N, Si ,P
(b) N, Si, C, P
(c) Si, P, C, N
(d) P, Si, N, C

Correct Answer:

Si, P, C, N

Explanation:

On moving along a period from left to right in periodic table, electrnegativity increases ( due to decrease in size). While on moving downward in a group, electronegativity decreases.
Thus, the correct order of electronegaticity is
Si > P > C > N
(1.8) (2.1) (2.5) (3.0)
