Question

Write chemical formula of two consecutive members of a homologous series and state the part of these compounds that determines their physical properties and chemical properties . P lz explain .

Answer 1

two consecutive members of homologous series are CH3OH and C2H5OH. the part which determines their physical and chemical properties is -OH and it shows the functional group-alcohol.

Answer 2

The chemical formula of two consecutive members of the homologous series of aldehydes is CH3-CHO and CH3-CH2-CHO.

Explanation:

• Aldehydes is CH3-CHO and CH3-CH2-CHO are the two consecutive members they are homologous series of aldehyde is methanal, ethanal.
• Also known as formaldehyde and acetaldehyde.
• In this series, each successive compound differs from the previous one by a $-CH2$group.
• They are better known as Aldehydes and are organic compounds that contain a carbonyl functional group, C=O.
• The carbon atom of the aldehyde group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.
