Question

Which functional group is found in methyl ethanoate?

Answer 1

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.

Answer 2

Answer:

The functional group found in methyl ethanoate contains a central carbon which is double bonded to O above, and single bonded to R below left and to O R prime below right.

Explanation:

Methyl ethanoate has a molecular  formula of CH3COOCH3. It is one of the simplest esters. The functional group of all esters contains a central carbon atom with double bond to an oxygen atom, single bond to a R group which could be methyl, ethyl, propyl and so on; and single bond to a R' group received from the carboxylic acid.

AN ester is formed from the reaction of an alkanol with carboxylic acid where water is also formed. The reaction is called ESTERIFICATION REACTION, and it is a reversible reaction.

Alkanol + carboxylaic acid <-------> ester + water

the ester contains a -COO- as their functional group. A polar carbonyl group amd two C-O single bonds attached to the same oxygen atom.

The alkyl groups R and R' may be same or different for example methyl ethanoate, CH3COOCH3, and ethyl ethabnoate, CH3COOC2H5.
