Which best describes the functional group in an aldehyde?



A. a carbonyl group inserted into the main chain

B. an –OH group and a carbonyl group attached to the main chain

C. a carbon chain with a carbonyl group bonded to one end

D. a carboxylic acid bonded on each side to a carbon chain

Respuesta :

C. a carbon chain with a carbonyl group bonded to one end 

Answer : The correct option is, (C) a carbon chain with a carbonyl group bonded to one end.

Explanation :

An aldehyde is an organic compound which contain a functional group with (-CHO) i.e R-CHO

R-CHO functional group consists of a carbonyl center that means a carbon which is double-bonded to the oxygen. The carbon of this carbonyl group bonded with the hydrogen to one end and a carbon chain, (R) to another end.

Some examples of an aldehydes are formaldehyde [tex](HCHO)[/tex], acetaldehyde [tex](CH_3CHO)[/tex]

Therefore, the correct answer is, (C)
