Question

Number of C-atoms in second member of an ester

Answer 1

Three in methyl ethaonate.

Answer 2

The second member of an ester has 3 carbon atoms.

Explanation:

• Ester are substances with general formula R$RCOOR_1$.
• In the formula, 'R' represents hydrogen or alkyl or aryl group whereas  '$R_1$' represent alkyl or aryl groups.
• Accordingly, the first member of the ester has 2 carbon atoms and its formula is $HCOOCH_3$.
• The molecular formula of second member of ester is $CH_3COOCH_3$. From the formula it is clear that it has 3 carbon atoms.
