Answer to Question #183815 in Organic Chemistry for Fanta

Question

How many hydrogen atoms would be in a molecule of an alkane containing 15 carbon atoms ?

Answer 1

The general formula for alkanes is $C_nH_{2n+2}$

Substitute $n=15$

we get, $C_{15}H_{32}$

So, 32 Hydrogen atoms  would be present in a molecule of an alkane containing 15 carbon atoms.
