Question

Two organic compounds A and B have the same molecular formula $C_6{H}_{12}$. Write the names and structural formulae:
(a) If A is a cyclic compound
(b) If B is an open chain compound
(c) Which compound contains single bonds as well as a double bond?
(d) Which compound contains only single bonds?

Answer 1

(a) If A is a cyclic compound, then $C_6{H}_{12}$. is the molecular formula of the compound named cyclohexane.
The structural formula is as follows:


(b) If B is an open chain compound, then $C_6{H}_{12}$ is the molecular formula of the compound named hexene.
The structural formula is shown below:

(c) Hexene (B) is an unsaturated hydrocarbon comprising both single-bonded and double-bonded carbon atoms.

(d) Cyclohexane is an alkane which contains only single-bonded carbon atoms.
