Question

what is homologous series of carbon compounds classify following carbon compounds into two homologous series and name them c3h4 , c3h4, c4h6, c4h6, c5h8, c5h10

Answer 1

There are 3 homologous series of Carbon compound's , these are =
Alkanes
Alkenes
Alkynes
in your question you have repeated c3h4 and c4h6 (correct it )
by the way you can use the general formula of the series to find it
General formula are -
Alkanes - CnH2n +2
Alkenes - CnH2n
Alkynes - CnH2n -2
(n is the subscript here )
WISH IT HELPS : )
n is the number of atoms
C is the carbon
H is the hydrogen
and 2 is added and subtracted from hydrogen atoms number only .

Answer 2

Homologous series are group of organic compounds with same fuctional group and general formula but their structures vary by increase or decrease in -CH2 group in the main chain.
