(b) One

(c) Two

(d) Three

To determine

The correct option for the statement “How many oxygen atoms are bonded to the carbon of the carbonyl of the ester functional group?”

Answer to Problem 8RAT

The correct option for the statement “How many oxygen atoms are bonded to the carbon of the carbonyl of the ester functional group?” is option (c).

Explanation of Solution

The ester functional group contains the formula ${\text{RCOOR}}^{\text{'}}$ where R and ${\text{R}}^{\text{'}}$ are the alkyl or aryl groups. The structure of an ester functional group is shown below.

Fig.(1)

In the above structure, the number of oxygen atom present is two.

The carbonyl carbon atom is mainly bonded one oxygen atom through double bon and another oxygen atom through single bond.

Thus, two oxygen atoms are bonded to carbon of the carbonyl of the ester functional group.

Conclusion:

Therefore, the correct option for the statement “How many oxygen atoms are bonded to the carbon of the carbonyl of the ester functional group?” is option (c).
