Question

The alcohols, methanol, ethanol, propanol, butanol, etc. form a homologous series. This means that they have:

• A. similar chemical properties, but gradually changing physical properties
• B. similar physical properties, but gradually changing chemical properties
• C. the same molecular formula, but different physical properties
• D. similar physical properties and the same structural formula

Answer 1

The correct option is A similar chemical properties, but gradually changing physical properties

A homologous series is a group of chemicals which have similar chemical properties and they share the same general formula. The physical properties of the members of the series vary gradually with increase in their atomic mass.
