Answer :
In alkane, number of hydrogen atom = 2n + 2
Where, n = number of carbon atoms
So, it would be: 2(8)+2 = 16+2 = 18
In short, Your Answer would be Option A
Hope this helps!

Answer;
A. 18 hydrogen atoms
Explanation;
- Alkanes are group of hydrocarbon that are saturated. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
- The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.
- Therefore, an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. Thus, the formula of the hyrocarbon will be; C₈H₁₈.
