Question

Fill in the blanks.
Alkane which has eight carbon atoms has _______ number of hydrogen atoms.
[1 Mark]

Answer 1

Solution:
eighteen [1 Mark]

Alkanes are saturated in nature and contain only single bonds. The general formula of an alkane is $C_n{H}_{2n+2}$ where n is the number of carbon atoms.
In the question, the number of carbon atoms is eight. Hence, the molecular formula of the compound will be $C_8{H}_{18}$.
