Question

The distance between the two adjacent carbon
atoms is largest in
(a) benzene (b) ethene
(c) butane (d) ethyne

Answer 1

The distance between two adjacent carbon atoms is more in Benzene.

Explanation:

(i) Benzene – Here the approximate distance is around 1.39 A. benzene has double bonds that are arranged in alternate orders and in between the carbon atoms. So it is obvious that here the carbon and carbon bond is alternate.

(ii) Ethene – In case of ethene the single double bond is present in between two adjacent carbon atoms. So the distance is less than benzene.

(iii) Butane – here also a single bond exists in between two adjacent carbon atoms so the distance is less.

(iv) Ethylene also has a triple bond present in between two carbon atom, which is less in distance as compared to benzene.  

So the correct answer is (A) Benzene.
