Question

Alkynes are isomeric with cycloalkanes containing the same number of carbon atoms.

• A. True
• B. False

Answer 1

The correct option is B False

Simple cycloalkanes, that is those without any additional branches attached, have the general formula: $C_n{H}_{2n}$. This is also the general formula of the linear alkenes.

'n' represents the number of carbon atoms in the cycloalkanes and must be a whole number greater than 2. Since both cycloalkanes and alkenes have the same general formula indicating the same number of carbon and hydrogen atoms, are known to be the isomers of each other.
