Correct Answer: Option D

Explanation

The general formula for alkanes is \(C_nH_{2n}+2\). For an alkane with 49 carbon atoms (n = 49), the number of hydrogen atoms can be calculated as follows:

Number of hydrogen atoms (H) = 2n + 2
Number of hydrogen atoms (H) = 2 * 49 + 2
Number of hydrogen atoms (H) = 98 + 2
Number of hydrogen atoms (H) = 100

So, an alkane with 49 carbon atoms contains 100 hydrogen atoms.
