Question

15. Among the following species, how many are
aromatic in nature?

(1) 5
(2) 4
(4) 3
(3) 6​

Answer 1

Explanation:

Given -

• Compounds

To Find -

• How many are Aromatic in nature ?

As we know that :-

• All the compounds obey the Huckel’s Rule, i.e all the aromatic compounds should have the (4n+2)π electron.

Now,

Let's Check all the compound and check that the compound is obeying Huckel's Rule or Not.

Compound 1)

Compound 1 contain 4 π electron. It is not obeying Huckel's Rule.

Compound 2)

Compound 2 contain 2 π electron. It is obeying Huckel's Rule.

Compound 3)

Compound 3 contain 4 π electron. It is not obeying Huckel's Rule.

Compound 4)

Compound 4 contains 6 π electron. It is obeying Huckel's Rule.

Compound 5)

Compound 5 contains 10 π electron. It is obeying Huckel's Rule.

Compound 6)

Compound 6 contains 10 π electron. It is obeying Huckel's Rule.

Compound 7)

Compound 7 contains 6 π electron. It is obeying Huckel's Rule.

Hence,

Compound 2,4,5,6,7 are obeying Huckel's Rule.

Therefore,

They are Aromatic compounds.

Hence,

This question contains 5 Aromatic compounds.

Therefore,

Option 1) is correct.
