Question

Write the IUPAC name of the next homologous series of
CH2 – OH –CH2– CH3
and write its
molecular formula

Answer 1

Answer:

Butan-1-ol

Explanation:

The one in the question consists of 3 carbon atoms and a hydroxy group at the first position, that is propan-1-ol. So the next homologue will consists of one more carbon atom, hence the answer.

Answer 2

The IUPAC name of the next compound of the given homologous series is Butan-1-ol (CH3-CH2-CH2-CH2-OH).

- The name of the given compound is propan-1-ol (CH3-CH2-CH2-OH).

- It is associated with the homologous series of alcohols.

- The next compound in a homologous series contains one -CH2 group more than the previous compound.

- Hence, the compound butan-1-ol is the next homologue of the given series.

- Its formula is written as CH3-CH2-CH2-CH2-OH (which can also be shown as C4H9OH).
