(alkynes, alkenes, or alkanes)

Alkanes = > CH4, C10H22

Alkenes = > C2H4, C3H6

Alkynes = > C2H2

Explanation:

Alkanes are saturated hydrocarbons with general formula CnH2n+2

Alkenes are unsaturated hydrocarbons with general formula CnH2n

Alkynes unsaturated hydrocarbons with general formula CnH2n-2

With these ideas in mind, let us answer your question given above.

1. When n = 1

Alkanes = > CnH2n+2 = > C1H (2x1) + 2 = > CH4.

2. When n = 2

Alkanes = > CnH2n+2 = > C2H (2x2) + 2 = > C2H6

Alkenes = > CnH2n = > C2H (2x2) = > C2H4

Alkynes = > CnH2n-2 = > C2H (2x2) - 2 = > C2H2

3. When n = 3

Alkanes = > CnH2n+2 = > C3H (2x3) + 2 = > C3H8

Alkenes = > CnH2n = > C3H (2x3) = > C3H6

Alkynes = > CnH2n-2 = > C3H (2x3) - 2 = > C3H4

4. When n = 10

Alkanes = > CnH2n+2 = > C10H (2x10) + 2 = > C10H22

Alkenes = > CnH2n = > C10H (2x10) = > C10H20

Alkynes = > CnH2n-2 = > C10H (2x10) - 2 = > C10H18

From the above illustrations

Alkanes = > CH4, C10H22

Alkenes = > C2H4, C3H6

Alkynes = > C2H2
