Question

“Alkenes form a homologous series" Explain. GIVING ALL MY POINTS PLEASE DONT JUST GIVE A STRAIGHT UP GOOGLE ANSWER...

Answer 1

Answer:

see below

Explanation:

homologous series : the successive members of carbon compounds differ by group - CH2 in their chains.

Ex : Alkenes : CnH2n

for n = 2 ; C2H4 : ethene

for n = 3 ; C3H6 ; propene

for n = 4 ; C4H8 ; butene

and so on....

now observe that.....

C2H4 + CH2 = C3H6

C3H6 + CH2 = C4H8......

the physical properties have a gradual change & chemical properties show a common similarly in these homologous series.
