प्रश्न
A saturated hydrocarbon has fifty hydrogen atom in its molecule. The number of carbon atoms in its molecule will be
(a) twenty five
(b) twenty four
(c) twenty six
(d) twenty seven

उत्तर
twenty four
Alkanes are saturated hydrocarbons that have the general formula CnH2n+2. According to the question, the number of hydrogen atoms is 50, i.e., 2n+2=50.
∴ n = 48/2 = 24
