Question

A saturated hydrocarbon has fifty hydrogen atoms in its moleucle. The number of carbon atoms in its molecule will be ______.

Options

• twenty five

• twenty four

• twenty six

• twenty seven

Answer 1

A saturated hydrocarbon has fifty hydrogen atoms in its moleucle. The number of carbon atoms in its molecule will be twenty four.

Explanation:

Alkanes are saturated hydrocarbons that have the general formula C_nH_2n+2. According to the question, the number of hydrogen atoms is 50, i.e., 2n+2=50.
∴ n = 48/2 = 24
