Question

Bad conductor of electricity is:
  1. HCl
  2. HI
  3. H2F2
  4. HBr

A
H2F2
B
HCl
C
HI
D
HBr
Solution
Verified by Toppr

Fluorine is the most electronegative element. So the H-F bond will be stronger than H-Cl, H-Br, H-I. Due to this H2F2 can not be ionized easily. Hence H2F2 is a bad conductor of electricity.
