Question

Arrange the following elements in increasing order of electronegativity: 

N, O, F, C, Si 

Choose the correct answer from the options given below: 

(1) Si < C < N < O < F 

(2) Si < C < O < N < F 

(3) O < F < N < C < Si 

(4) F < O < N < C < Si

Answer 1

Correct option is (1) Si < C < N < O < F 

Electronegativity increases across the period on moving left to right. It decreases on moving down the group.

The correct option is Si < C < N < O < F
