Functional Groups
Q1: What are Functional Groups?
Answer:
A functional group is an atom or a group of atoms that makes a carbon compound or an organic compound reactive and determines its properties. For example, alcohal, aldehyde, ketones, ether, carboxylic acid, etc.
Q2: How many Functional Groups are present in Acetic Acid?
Answer:
As the molecular formula for acetic acid is CH3COOH, the only functional group present is carboxylic acid (-COOH).
Q3: What are the main Functional Groups present in Carbohydrates?
Answer:
Carbohydrates are either polyhydroxy aldehydes or polyhydroxy ketones; thus, functional groups present in carbohydrates are,
- Alcohals
- Aldehydyes
- Ketones
Q4: What is a Carboxy Group?
Answer:
By combining carbonyl (-CO-) and hydroxyl (-OH), we get the carboxyl group (-COOH). It is also known as carboxylic acid and is one of the most useful groups in organic chemistry.
Functional Groups
Functional Groups if added to hydrocarbons change their functionality and properties. A hydrocarbon is a compound made up of hydrogen and carbon, which can be either saturated or unsaturated. A saturated hydrocarbon is one in which the carbon atoms are joined by only a single bond and an unsaturated hydrocarbon is one in which a double or triple bond between carbon atoms is present. Generally, a saturated hydrocarbon is very less reactive, but when another ‘atom’ or ‘group of atoms’ is attached to it, the resulting molecule becomes highly reactive depending on the attached group. The other ‘atom’ or ‘group of atoms in a carbon compound is called a functional group.
