Question

Branching by ester and amide bonds is typically by a:
(A) Hydrolysis reaction
(B) Condensation reaction
(C) Synthesis reaction
(D) Displacement reaction

Answer 1

Hint: The organic compound which contributes to the flavors and even at some times aromas in the fruits and the flowers are known as esters. The natural flavors and the aromas are produced as a result of the complex mixture of various compounds.

Complete Answer:
Esters are the organic compounds which contribute to flavors and aromas in fruits or flowers. Some examples, the natural orange aroma consist of 30 different esters which includes 1 carboxylic acid, 34 aldehydes and ketones and 36 hydrocarbons and 34 alcohols. The food industry always tries to mimic the natural flavors and in this case they use esters. Branching by esters and amide bonds results from the formation of carbon – carbon or different types of covalent bonds. And the branching in ester and amide bonds is typically by a condensation reaction which produces one molecule of water from the formation of one bond. The condensation reaction in organic chemistry is a type of reaction which proceeds in a stepwise manner and produces the additional product usually during equilibrium and a water molecule is produced.

Hence the correct answer is option (B) i.e. Branching by ester and amide bonds is typically by a condensation reaction.

Note: The structure of an ester is an organic compound with an alkoxy group which is –OR group which is attached to the carbonyl group. The R group present is a hydrogen group, and alkyl group, and an aryl group.
