Write a short note functional group
Answers
What are functional groups ?
Functional groups are an atom or groups of atoms that determine the properties (physical and chemical) of carbon compounds.
Some examples of functional groups:
- Halogens:
-Cl
-Br
-I
-F
- Alcohol:
R-OH (R is a methyl group)
- Ketone:
|
C = O

- Aldehyde:
R-CHO (R is a methyl group)
- Carboxylic Acids
R-COOH (R is a methyl group)
More to Know:
1. A methyl group has the general formula CₙH₂ₙ₊₁. It has one single bond open where a monovalent atom (eg. Cl, H etc) or group of atoms (OH, COOH etc.) may join.
2. A series of atoms that differs by a CH₂ and have the same functional group is called a homologous series. The properties of all the members of one homologous series are similar. (However, there is a gradual change in physical properties due to increase in mass of members.)
