Question

1-Chloropropane and 2-Chloropropane are:

• A. Metamerism
• B. Functional isomerism
• C. Position isomerism
• D. Tautomers

Answer 1

The correct option is B Functional isomerism

Compounds having the same molecular formula but different physical and chemical properties are called isomers. 1- Chloropropane and 2- Chloropropane has the same molecular formula $C_3{H}_{7}Cl$. Therefore, they are isomers to each other.

• Functional isomerism- Compounds having the same molecular formula but having a difference in their functional groups.
• Chain isomerism- Compound having the same molecular formula but the difference in the chain structure.
• Position isomerism- If the position of the functional group is different in the compound having the same molecular formula and same functional group.

In 1-Chloropropane and 2-Chloropropane, the position of chlorine is different. Hence, they are position isomers.
