Question

The structural formula of an ester is Figure
Write the formula of the acid and the alcohol from which it is formed.

Answer 1

Answer:

alcohol = ethyl alcohol C2H5OH

acid= ethanoic acid CH3COOH

Answer 2

Ethyl Ethanoate is the Ester Representing Structural Formula

Explanation:

Ethyl ethanoate or $CH_3COOC_2H_5$ is the ester corresponding to the structural formula. And these have been sweet-smelling and can be produced when carboxylic acid reacts with alcohol but the reaction needs the presence of conc. sulphuric Acid.

(a) $CH_3COOH$ is the formula of Ethanoic Acid.

(b) $CH_3-CH_2-OH$ is the formula of Ethanol (Alcohol)

The reactants and products with the chemical reaction are as under -

$CH_3COOH$+$CH_3CH_2OH$ ⇒ Conc. $H_2SO_4$⇒ $CH_3COOCH_2CH_3$+$H_2O$
