Question

Classify the following as Alkane,Alkene,or Alkyne:-
CH 4 , C 2 H 4, C 2 H 2, C 3 H 8 , C 4 H 10 , C 5 H 10 , C 5 H 8 , C 6 H 10

Answer 1

Alkane have single bond, alkene have double bond, alkyne has triple bond.

CH4 is alkane, . Alkane has general formula CnH2n+2 where n is no of carbon atoms. ( If C is 1 then H is 2×1 +2 =4. ). Similarly, alkene is CnH2n, alkyne is CnH2n-2. I hope now u can identify them.

Please mark it as brainiest. If you like the answer

Answer 2

Alkane -: CH4, C3H8, C4H10.

Alkene -: C2H4, C5H10.

Alkyne -: C2H2, C5H8, C6H10.
