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. Cemical bond formation takes plane when forces of attraction overcome the forces of repulsion . |
Answer» Correct Answer - 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 . |
