a) Alcohol
Interpretation:
The structure of the simple molecules containing the following
Concept introduction:
In chemistry, an alcohol is an organic compound that contain hydroxyl group (OH) attached to carbon atom. The term alcohol mainly refers to ethanol, which is used as a drug and it is the main alcohol in alcoholic beverages.
b) Aromatic Ring
Interpretation:
The structure of the simple molecules containing the following functional group are to be proposed.
Concept introduction:
An aromatic ring contains conjugated planar ring system. They were initially called aromatic because of its fragrance. But, the term “aromaticity” now refers to the stable molecule due to resonance. For example-Benzene.
c)
Interpretation:
The structure of the simple molecules containing the following functional group are to be proposed.
Concept introduction:
A carboxylic acid is an organic compound that contains a carboxyl group (C=O)OH. The general formula of a carboxylic acid is R–COOH.
d) Amine
Interpretation:
The structure of the simple molecules containing the following functional group are to be proposed.
Concept introduction:
e) Both
Interpretation:
The structure of the simple molecules containing the following functional group are to be proposed.
Concept introduction:
Amines are formally derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines). It contain a NH2 group.
f) Two double bonds
Interpretation:
The structure of the simple molecules containing the following functional group are to be proposed.
Concept introduction:
Amines are formally derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines). It contain a NH2 group.
