Question

Arrange the following elements in increasing order of electronegativity:

N, O, F, C, Si

Choose the correct answer from the options given below:

Options

A.$O < F < N < C < Si$
B.$F < O < N < C < Si$
C.$Si < C < N < O < F$
D.$Si < C < O < N < F$

Solution

Sol. [Key Concept: Electronegativity trend]

Electronegativity generally increases from left to right across a period and decreases down a group. Silicon is below carbon, and the second period sequence rises from C through N and O to F.

Therefore Si < C < N < O < F, option (3).
