Question

Consider molecules with the molecular formula C4H8O2 Choose the structural formula for a molecule with this molecular formula that contains _______(a) A carboxyl group(b) An ester group(c) A ketone group and a 2° alcohol(d) An aldehyde and a 3° alcohol

Answer 1

A. An ester group

Step-by-step explanation:

esters are organic compounds which are formed from the dehydration reaction of a carboxylic acid and an alcohol with its general formula of RCOOR'; where R and R' may or may not be the same alkyl group. Examples are: ethyl ethanoate - CH3COOC2H5, ethyl butanoate - C3H7COOC2H5 etc.

Application of esters include:

Fats are generally triesters derived from glycerol and fatty acids.

Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries.

Because of this characteristic aroma, they are used in the production of perfumes and fragrances.
