1) same amount of carbon atoms.

That is why it is still called butane and butene.
but- always signifies 4 carbons

Answer: Option (1) is the correct answer.

Explanation:

A hydrocarbon that contains only single bonds is known as alkane. Their general formula is \(C_{n}H_{2n+2}\), where n is the number of carbon atoms.

For example, butane (\(CH_{3}CH_{2}CH_{2}CH_{3}\)) is an alkane.

Whereas a hydrocarbon that contains at least one double bond is known as an alkene. Their general formula is \(C_{n}H_{2n}\).

For example, 2-butene (\(CH_{3}CH=CHCH_{3}\)) is an alkene.

Hence, there are same number of carbon atoms in both butane and 2-butene.
