Identify the Following as either Alkanes, alkynes or alkenes

CH4:
C2H4:
C3H6:
C2H2:
C10H22:

The answer to your question is below

Explanation:

To solve this problem use the general formulas for Alkanes, Alkenes, and Alkynes.

Alkanes           Cn H(2n + 2)

Alkenes           Cn H (2n)              "n" is the number of Carbons

Alkynes            Cn H (2n - 2)

a) CH₄             C₁ H 2(1) +2   = C₁H₂ + ₂ = CH₄       Alkane

b) C₂H₄            C₂ H₂(₂)                                           Alkene

c) C₃H₆             C(₃) H₂ (₃)                                        Alkene

d) C₂H₂            C₂ H₂(₂) - 2  = C₂H₄ - ₂ = C₂H₂        Alkyne

e) C₁₀H₂₂          C₁₀ H₂(₁₁)                                          Alkene

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
