In X - H----Y , both X and Y are electronegative elements

Options

A. Electron density on X will increases and on H will decreases
B. In both electron density will decrease
C. In both electron density will increase
D. Electron density will decrease on `X` and will increase on `H`

Answer

a

Explanation

In `X - H----Y` , both X and Y are electronegative elements (i.e. atract the electron pair) , then electron density on X will increases and on H will decreases.
