An is a hydrocarbon in which one or more hydrogen atoms is replaced by a -coh group. a. aldehyde b. alcohol c. ester d. amino acid

Answer :  The correct option is, (A) Aldehyde

Explanation :

Alcohol group : It is the class of organic compound in which the hydroxy (-OH) group is attached to a hydrocarbon is known as alcohols.

The general representation of alcohol are, .

For example : is obtained when one hydrogen atom is replaced by group.

Amino acid : Amino acid are the acid that contains two functional groups which are carboxylic group, and ammine group, .

The bond present between the two amino acid is a peptide bond. The peptide bond is formed between the nitrogen of one amino acid and carbon of another amino acid.

Ester group : It is the class of organic compound in which the group is attached to a hydrocarbon is known as ester.

The general formula of ester are, . It is directly attached to the two alkyl group of carbon.

Aldehyde group : It is the class of organic compound in which the (-CHO) group is attached to a hydrocarbon is known as aldehyde.

The general representation of aldehyde are, .

For example : is obtained when one hydrogen atom is replaced by group.

Hence, the correct option is, (A) Aldehyde

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
