Answer 2

Answer:  The molecular formula of given compounds are:

pentane: $C_{5} H_{12}$

pentene: $C_{5} H_{10}$

pentyne: $C_{5}H_{8}$

Explanation:

• Only hydrogen and carbon are present in organic molecules known as hydrocarbons.

• The hydrocarbons containing only C-C single bonds and ending with 'ane' are the saturated hydrocarbons or alkanes with general formula $C_{n} H_{2n + 2}$.
• The hydrocarbons containing C-C double bonds and triple bonds and ending with 'ene' and 'yne' are the unsaturated hydrocarbons known as alkenes and alkynes with general formula $C_{n} H_{2n}$ and $C_{n} H_{2n - 2}$ respectively.

• As 'pent' corresponds to $5$ carbon atoms, molecular formula of pentane is $C_{5} H_{12}$
• Molecular formula of pentene and pentyne are $C_{5} H_{10}$ and $C_{5}H_{8}$.
