Answer
In organic chemistry, an alkane is a saturated hydrocarbon containing only single bonds. To identify the alkane among the given options, we need to examine the general formula for alkanes, which is CₙH₂ₙ₊₂.
Option A: C₄H₁₀
Here, n = 4.
Following the formula:
C4H10=C4H2(4)+2=C4H10
This fits the alkane formula, so A is a valid alkane.
Option B: C₅H₁₂
Here, n = 5.
Following the formula:
C5H12=C5H2(5)+2=C5H12
This fits the alkane formula, so B is also a valid alkane.
Option C: C₁₄H₃₀
Here, n = 14.
Following the formula:
C14H30=C14H2(14)+2=C14H30
This also fits, so C is an alkane as well.
Option D: C₈H₁₄
Here, n = 8.
Following the formula:
C8H14=C8H2(8)+2=C8H18
This does not fit the alkane formula, so D is not an alkane.
In conclusion, both A, B, and C are representative of alkanes, but since the question specifically asks for one option, we will choose the first correct option listed, which is A.
