Question

give names of functional group
R-CHO , R-CO-R , R-COOH, R-OH

Answer 1

Answer:

R-CHO - ALDEHYDE

R-CO-R - KETONE

R-COOH - CARBOXYL GROUP

R-OH - ALCOHOL

Answer 2

Explanation:

R-CHO = Aldehyde group

R-CO-R = Ketone group

R-COOH = Carboxylic acid group

R-OH = Alcohol group

Additional information -

• An atom or a group of atoms which makes a carbon compound (or organic compound) reactive and decide its properties (or function) is called a functional group.

Alcohol group :-

• The alcohol group is also known as alcoholic group or hydroxyl group.
• The compounds containing alcohol group are known as alcohols.
• The general formula of an alcohol group can be written as R-OH (where R is an alkyl group like CH3, C2H5, etc., and OH is the alcohol group)

Examples :-

• CH3OH - Methanol
• C2H5OH - Ethanol
• C3H7OH - Propanol

Aldehyde group :-

• The Aldehyde group is sometimes called aldehydic group.
• The compounds containing Aldehyde group are known as Aldehydes.
• The general formula of an Aldehyde group can be written as R-CHO (where R is an alkyl group like CH3, C2H5, etc., and CHO is the Aldehyde group)

Examples :-

• HCHO - Methanal
• CH3CHO - Ethanal
• C2H5CHO - Propanal

Ketone group :-

• The Ketone group is sometimes called ketonic group.
• The compounds containing Ketone group are known as Ketones.
• The general formula of an Ketone group can be written as R-CO-R (where R is an alkyl group like CH3, C2H5, etc., and CO is the Ketone group)

Examples :-

• CH3COCH3 - Propanone
• CH3COCH2CH3 - Butanone

Carboxylic acid group :-

• The Carboxylic acid group is sometimes called carboxyl group.
• The compounds containing Carboxylic acid group are known as Carboxylic acids or organic acids.
• The general formula of an Carboxylic acid group can be written as R-COOH.

Examples :-

• HCOOH - Methanoic acid
• CH3COOH - Ethanoic acid
