• 196

Answer 1

A hydrocarbon having one double bond has 100 carbon atoms in its molecule. The number of hydrogen atoms in its molecule will be 200.

Explanation:

Alkenes have double bonds and are represented by the formula C_nH_2n. Here, 'n' is the number of carbon atoms in its molecule. Therefore, substituting 'n' with 100 in the formula of the alkenes, we get 200 hydrogen atoms.
