12. (i) Organic acids have the functional group :
(A) -OH
(B) –COOH
(C CHO
(D) CO
Answers
a} Organic acids are the organic compounds with the acidic properties, classified based on the number of carboxylic functions. ... Organic acids vary in the number of hydroxy or carboxyl functional groups and carbon-carbon double bonds in their structures.
b)The carboxyl (COOH) group is so-named because of the carbonyl group (C=O) and hydroxyl group. Alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids. The oxidation of organic compounds generally increases the number of bonds from carbon to oxygen, and it may decrease the number of bonds to hydrogen.
c)Aldehydes. Aldehyde: An aldehyde is characterized by the presence of a carbonyl functional group at the end of a compound's carbon skeleton. An aldehyde is an organic compound that contains a carbonyl group with the central carbon bonded to a hydrogen and R group (R-CHO).
d)In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound.
