Answer:
Answer is C₈H₁₄
Explanation:
The general molecular formula of alkanes (saturated hydrocarbons) is:
CₙH₂ₙ₊₂
Where n = number of carbon atoms.
The general molecular formula of alkenes (unsaturated hydrocarbons) is:
CₙH₂ₙ
The general molecular formula of alkynes (unsaturated hydrocarbons) is:
CₙH₂ₙ₋₂
Now let us check the formula of given compounds
a)C₅H₁₂
n = 5
2n=10
2n+2=12
so this is an alkane, saturated hydrocarbon.
b)C₇H₁₆
n = 7
2n=14
2n+2=14
so this is an alkane, saturated hydrocarbon.
c)C₆H₁₄
n = 6
2n=12
2n+2=14
so this is an alkane, saturated hydrocarbon.
d) C₈H₁₆
n = 8
2n=16
2n+2=18
2n-2=14
so this is an alkyne, unsaturated hydrocarbon.
