Question

How many hydrogen atoms are in an acyclic alkane with 15 carbon atoms?

Answer 1

In the above question, we are asked how many hydrogen atoms are present in an acyclic alkane with 15 carbon atoms. We can use the general formula of alkane to know how many hydrogen atoms will be present.

Complete step by step solution
We have the general formula of alkane as ${{{C}}_{{n}}}{{{H}}_{{{2n + 2}}}}$ .
When the number of carbon atoms is 15, the number of hydrogen atoms is ${{2n + 2 = 2 \times 15 + 2 = 32}}$ . It can be represented as ${{{C}}_{{{15}}}}{{{H}}_{{{32}}}}$
Hence, there are 32 hydrogen atoms present in an acyclic alkane with 15 carbon atoms.

Additional Information
Alkanes are the major constituents of crude oil and the most important constituents of most petroleum products. Alkanes are also known as saturated or saturated hydrocarbons. The carbon atoms which form the carbon backbone are linked together to form a chain (linear or branched alkanes), a circle (cyclic alkenes), or a mixture of both. The alkanes are distinguished from the other hydrocarbons because they are completely saturated with hydrogen. This means that no additional hydrogen atoms can be added to these hydrocarbons without destroying the carbon backbone. A linear or branched alkane that has four carbon atoms will also have 10 and only 10 hydrogen atoms. Linear alkanes, i.e., alkanes whose carbon atoms are arranged in a straight chain or row, are called normal paraffins, normal alkanes, or n-alkanes. The branched alkanes are often referred to as isoparaffins or isoalkanes.

Note
The general of the given compound must be remember, that is,
Alkane is ${{{C}}_{{n}}}{{{H}}_{{{2n + 2}}}}$
Alkene is ${{{C}}_{{n}}}{{{H}}_{{{2n}}}}$
Alkyne is ${{{C}}_{{n}}}{{{H}}_{{{2n - 2}}}}$
