Text Solution

Verified by Experts

The correct Answer is:
D
When water decomposed volume ratio of `H _(2)` to `O_(2)` in 2:1, but the mass ratio of `H_(2)` to `O_(2)` is 2:1, but the mass ratio is 1:8, water is a polar compound, its dipole moment is 1.85 D, but water is bad conductor of electricity.
