Correct order of electronegativity of N, P, C and Si on Pauling scale is :
A
N > P > C > Si
B
C > Si > N > P
C
N < P < C < Si
D
N > C > P > Si
Answer
N > C > P > Si
Explanation
Solution
Electronegativity of elements generally increases across the period (less increase) and decreases down the group (more decrease).
Si = 1.8, P = 2.1, C = 2.5, N = 3.0. So, the correct increasing order is Si < P < C < N.
