Question

Which of the following compounds is an example of homologous series of alcohols?

• A. $C{H}_{3}OH$
• B. $C{H}_{3}C{H}_{2}OH$
• C. $C{H}_{3}C{H}_{2}C{H}_{2}OH$
• D. All of the above

Answer 1

Answer: (D)

All of the above

Compounds of homologous series differ by $C{H}_2$ from their consecutive members. Homologous series of alcohols include methanol $\left(C{H}_{3}OH\right)$, ethanol $\left(C{H}_{3}C{H}_{2}OH\right)$, propanol $\left(C{H}_{3}C{H}_{2}C{H}_{2}OH\right)$, butanol, pentanol, etc. So, all of the compounds in the options are homologous.

Hence, the correct option is D.
