Question

What is the chemical formula structure of ozone?

(a) O = O^+ – O^–

(b) O^– – O = O^+

(c) O = O^– – O^+

(d) O^– = O^+ – O

I got this question in exam.

I want to ask this question from P-Block Elements topic in portion P-Block Elements of Chemistry – Class 12

Answer 1

The correct choice is (a) O = O^+ – O^–

The explanation is: According to the Lewis dot-structure, the central oxygen atom shares a total of three electrons as a consequence of which it bears a positive charge. The oxygen to the right forms tends to attract a shared pair of electrons towards itself, thereby developing the negative charge.
