Question

43. Which of the following functional group is not present in “Atropine”: (1) Amine (2) Ester (3) Phenol (4) Benzene​

Answer 1

Answer:

Alkyne Ketone Carboxylic Acid Ester.

Answer 2

Option B)  Ester

Ester the following functional group is not present in “Atropine”.

• Among a group of organic molecules known as esters, alcohols and organic or inorganic acids are produced when ester reactions with water take place. The most typical esters come from carboxylic acids. German scientist Leopold Gmelin coined the word "ester" in the first part of the 19th century.
• An ester is ethyl acetate (also known as ethanoate). An ethyl group is used in place of the hydrogen on acetic acid's carboxyl group. Ethyl propanoate, propyl methanoate, propyl ethanoate, and methyl butanoate are other instances of esters. Fatty acid esters of glycerol are known as glycerides.
• The standard formula for esters is RCOOR′, where R may be an alkyl group, an aryl group, a hydrogen atom, or any combination of these. R′ may also be an alkyl group or an aryl group but not a hydrogen atom. (The mixture would be a carboxylic acid if the hydrogen atom were absent.)
• Esters can be employed as solvents in the chemical industry, but their primary applications are in flavourings and fragrances.
