(i) ethyne
(ii) ethene
(iii) benzene
(b) Write the molecular formula and structure of cyclohexane. How many covalent bonds are there in a molecule of cyclohexane?

Answer 1

Answer:

(a) Giving their structures, state the number of single bonds, double bonds and triple bonds (if any) in the following compounds

(i) ethyne

(ii) ethene

(iii) benzene

(b) Write the molecular formula and structure of cyclohexane. How many covalent bonds are there in a molecule of cyclohexane?

Answer 2

Answer:

(a) the correct answer will be 3rd option i.e benzene.

(b) A cyclohexane molecule has six carbon-carbon single bonds and twelve carbon-hydrogen single bonds. Therefore, there are 18 covalent bonds in one molecule of cyclohexane.

molecular formula:- C6H12
