Which of the following statements is not correct?

AOxygen molecule is paramagnetic with two unpaired electrons.
BSulphur shows maximum covalency of four.
Correct Answer
COzone can be easily detected by mercury.
DBoth sulphurous and sulphuric acid are dibasic in nature.

Solution

Covelency of an atom is the number of covalent bonds that it can form.

While we are finding the maximum covalency of any element we should check the group of that element in the periodic table.

As sulphur is the element of 16 group elements ,so it's maximum covalency is 6 and also in its excited state it has 6 unpaired electrons thus it’s maximum covalency is 6.EX:In $$SF_6$$ the maximum valency is 6.
