Which of the following statement `(s)` is (are) true ? .

A

`CuCI` is more covalent than `NaCI`

B

`HF`is more polar than `HBr`

C

`HF` is less polar than `HBr`

D

Chemical bond formation takes plane when forces of attraction overcome the forces of repulsion .

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`HF` is more polar than `HBr` as `EN` of `F` is more than that of `Br`
` CuCI` is more covalent than `NaCI` as 18-electron shell of `Cu^(o+)([Ar]3d^(10))` is more `EN` because inner electrons have poor shielding effect on nucleus increasing the polarising power of nucleus .
