A neutral water molecule (H(2)O) in its ...

A neutral water molecule `(H_(2)O)` in its vapour state has an electric dipole moment of magnitudes `6.4xx10^(-30)C-m`. How far apart are the molecules centres of positive and negative charge?

A

`4xx10^(-10)`

B

`4xx10^(-11)`

C

`4xx10^(-12)`

D

`4xx10^(-13)`

Text Solution

Verified by Experts

The correct Answer is:
B
`p=q(2a) implies 2a =p/q =(6.4 xx10^(-30))/(1.6 xx10^(-19))=4 xx10^(-11)m`
