Question

Which of the following statement is true?

(a) Silicon exhibits 4 coordination number in its compound.

(b) Bond energy of F₂ is less than Cl₂.

(c) Mn(III) oxidation state is more stable than Mn(II) in aqueous state.

(d) Elements of 15^th gp shows only + 3 and +5 oxidation states.

Answer 1

Correct option (b) Bond energy of F₂ is less than Cl₂.

Explanation :

Fluorine is more reactive than chlorine. So bond energy of chlorine is greater than fluorine. Silicon exhibits 6 coordination number.

In aqueous state Mn(II) is more stable.
