NEET 2024 — Chemistry solution

NEET2024Chemistry

Arrange the following elements in increasing order of electronegativity: N, O, F, C, Si

Choose the correct answer from the options given below

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

Electronegativity increases across a period and decreases down a group. Among the listed elements: Si (period 3) is lowest; C, N, O, F belong to period 2 with EN increasing left to right.

$∴$ Si $<$ C $<$ N $<$ O $<$ F.
