The moon used to be connected with Earth. A meteor hit several billion years ago and split the Earth and Moon apart. This explains why they share the Sam properties.
Answer:
a. Alkene
b. Alkyne
c. Alkane
d. Alkyne
Explanation:
Hydrocarbons can be:
- Alkanes: all single bonds. Have the general formula CₙH₂ₙ₊₂.
- Alkenes: have a double bond. Have the general formula CₙH₂ₙ.
- Alkynes: have a triple bond. Have the formula CₙH₂ₙ₋₂.
a. C₈H₁₆
Alkene. n = 8 and 2n = 2.8 = 16,
b. C₄H₆
Alkyne. n = 4 and 2n-2 = 2.4-2 = 6.
c. C₇H₁₆
Alkane. n = 7 and 2n+2 = 2.7+2 = 16.
d. C₂H₂
Alkyne. n = 2 and 2n-2 = 2.2-2 = 2.
