Question

How many isomers exist that have the molecular formula C₄H₁₀?

1. three
2. one
3. four
4. none
5. two

Answer 1

Yes, two is the correct answer.

C₄H₁₀ is known as normal butane (n-butane) The other isomer is isobutane (i-butane or 2-methyl propane).

Answer 2

Two Each isomer has its own unique name: butane and isobutane. The reason that there are only two isomers is because this is how many structurally different compounds are possible.
