Question

Suppose an alkane had 30 hydrogen atoms. How many carbon atoms would it have?

a.
15 atoms
c.
14 atoms
b.
62 atoms
d.
28 atoms

Answer 1

The answer would be C - 14 atoms.

Answer 2

Answer: c. 14 atoms

Step-by-step explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula for these hydrocarbons is
`C_nH_(2n+2)` and they are called as alkanes.

Given: An alkane contains 30 hydrogen atoms

Thus we can write:

`2n+2=30`

`2n=28`

`n=14`

Thus the number of carbon atoms will be n which is 14.
