Question

Which of the following statements is true?
(a) HF is less polar than HBr
(b) Absolutely pure water does not contain any ions
(c) Chemical bond formation takes place when forces of attraction overcome the forces of repulsion
(d) In covalency transference of electron takes place.

Answer 1

(c) : Due to the higher electronegativity of F, HF is more polar than HBr pure water contains H⁺ and OH^– ions. In covalency, sharing of electrons between two nonmetal atoms takes place.
