1-butene has the molecular formula C4H8.
All possible structural isomers of 1-butene must have the molecular formula C4H8. 1-butene, 2-butene, 2-methylpropene and 4. cyclobutane are structural isomers. They have the same molecular formula, C4H8, but different structural formulae.

So please read carefully in question. So question is say that how many isomers is possible of butane you know question is going to only alkane isomers, not for alkene Cyclo so on. 2 isomer is possible Butane and 2 methy propane.

But the correct answer is 6.
# 1- Butene.
# 2- butene.
# Isobutylen.
# cyclobutane.
# methylcyclopropane.
# For 2-butene, we can further have cis-trans isomerism.
So, Cis-2- butene and trans-2- butene.
# 1- Butene.
# 2- butene.
# Isobutylen.
# cyclobutane.
# methylcyclopropane.
# For 2-butene, we can further have cis-trans isomerism.
So, Cis-2- butene and trans-2- butene.

1-butene.
Cis-2-butene.
Trans-2-butene.
Cyclobutene.
Methyl cyclopropane.
2-methyl butene.
That any one of these is not an isomer of C4H8.
So except for itself, it should.
Cis-2-butene.
Trans-2-butene.
Cyclobutene.
Methyl cyclopropane.
2-methyl butene.
That any one of these is not an isomer of C4H8.

1) CH2 = CH-CH2-CH3.
2) CH3-CH = CH-CH3.
3) C IS FORM,
&
4) Transform of CH2 = C(CH3)2.
2) CH3-CH = CH-CH3.
3) C IS FORM,
&
4) Transform of CH2 = C(CH3)2.

The number of isomers is 6 in which 4 is structural & 2 is geometrical isomers.

Isomer means the compounds of same molecular formula having different structures.
Jimmy said:

Not forget C is and trans form of CH3-CH = CH-CH3. Hence it have total 4 isomer.

Please tell me how to know the isomers of compounds. If any formulas are there?
