Question

define homologous series of organic compounds, mention any two characteristics of homologous series

Answer 1

homologous series have same molecular formula but different structural formula.
homologous series differ by ch3 groups
eg. CH3OH
ch3-ch2-ch3. r. ch3ch2ch2OH
|
OH

Answer 2

Answer:

Characteristics of organic compounds are as follows:

• These are mad up of only a few elements C, H, O, N, S, X. (Cl, Br, I)

• These involve covalent bonds.

• These are generally gases or liquids.

• They have low melting and boiling points.

• They are combustible.

• They show molecular reactions.

• They show isomerism.

• These are non - conductors of electricity.

• There are generally insoluble in water but soluble in organic solvents.
