The bond length of HCl molecule is 1.275...

The bond length of HCl molecule is 1.275 Å and its dipole moment is 1.03 D. The ionic character of the molecule (in per cent) is
(Charge of the electron`=4.8xx10^(-10)` esu)

A

100% ionic

B

83% covalent

C

50% covalent

D

40% ionic

Text Solution

Verified by Experts

The correct Answer is:
B
`(100xx1.02 xx 10^(-10))/(1.275 xx 4.8 xx 10^(-10)) = 16.66%` ionic (or) 83.4% covalent.
