Question
A hydrocarbon having one double bond has 100 carbon atoms in its molecule. The number of hydrogen atoms in its molecule will be
(a) 200
(b) 198
(c) 202
(d) 196

Solution
200
Alkenes have double bonds and are represented by the formula CnH2n. 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.
