Answer:
A central carbon is double bonded to O above, and single bonded to R below left and to O R prime below right.
Explanation:
Methyl ethanoate belongs to a homologous series in organic chemistry known as esters. A homologous series simply means a family of organic compounds. They always have the the same functional group and differ from each other by -CH2-functional group. The functional group is responsible for the chemical reactivity of the members of a particular homologous series.
The general formula for esters is RCOOR. Note that R and R may be the same or different. Hence, we have a central carbon atom, double bonded to an oxygen atom and also single bonded to R and OR respectively.
In the structure of methyl ethanoate, the O has a double bond with central carbon and is attached with the R group on the left, and with R prime on right with O. Thus, option B is correct.
Methyl ethanoate has been the organic compound with ester functional group as R-COO-R. The compound has been found to be present with the methyl as an R group, and another R group has been methyl. The functional group COO has been responsible for the reactivity of the compound.
The structure of methyl ethanoate has been shown in the image attached.
It has been consisted of an ester bond having central carbon attached to the O above with a double bond. It has the presence of a single R (methyl group) left to carbon, and R prime (methyl group) right to O. Thus, option B is correct.
