The electronegativity of the following elements increases in the order [AFMC 2011]
A.C, N, Si, P
B.N, Si, C, P
C.Si, P, C, N✓ Correct
D.P, Si, N, C
Explanation
Electronegativity is the measure of the tendency of an atom to attract the bonding pair of electrons towards them. The trend of electronegativity decreases down the group due to increase in atomic radius and increases from left to right in the period due to a decrease in size. Therefore, the correct is Silicon < Phosphorus < Carbon < Nitrogen .
