Question

How many different structural isomers are there for a hydrocarbon with the formula C₄H₁₀?

1) 1
2) 2
3) 3
4) 4

Answer 1

For a hydrocarbon with the formula C4H10, there are two structural isomers: n-butane and 2-methylpropane. So the answer is 2.

Step-by-step explanation:

The question pertains to the number of different structural isomers for a hydrocarbon with the formula C4H10. Structural isomers are compounds with the same molecular formula but different structural arrangements. For the given formula, there are two alkanes that qualify as structural isomers: n-butane and 2-methylpropane (or isobutane). Therefore, the correct answer to the question is 2).
