MCQ

Excited state of chlorine in $ClF_3$ is

✓
First
B
Second
C
Third
D
None

✓

Answer

Correct option: A.

First

a
ClF $_{3}$ is formed in the first excitation state of $Cl$.

The valence shell electron configuration of ground state of chlorine is $3 s ^{2} 3 p ^{5}$

The valence shell electron configuration of first excited state of chlorine is $3 s ^{2} 3 p ^{4} 3 d ^{1}$

This is followed by sp $^{3} d$ hybridization to form ClF $_{3}$
