Question
The electronegativity of the following elements increases in the order
- (a) C, N, Si, P
- N, Si, C, P
- (c) Si, P, C, N
- P, Si, N, C
The correct answer is: N, Si, C, P
Halogens have very high electron affinity. It may be rated that the electron affinity of fluorine is unexpectedly low 
. This may perhaps be due to small size of F atom. The value of electron gain enthalpies for 
and O are respectively 349, 333, 200 & 142 KJ / mol hence correct order is
