Answer 1

изомеры.  2) бутадиен-1, 3 и бутин-1

Answer 2

Isomers of the given compounds:

1) 2-methylbutene and pentane: - 2-methylbutene is an alkene with the molecular formula C5H10. It has a double bond between carbon atoms 2 and 3, and a methyl group attached to carbon atom 2. - Pentane is an alkane with the molecular formula C5H12. It consists of a straight chain of five carbon atoms with no double bonds or branches. - Therefore, 2-methylbutene and pentane are isomers of each other.

2) Butadiene-1,3 and butyne-1: - Butadiene-1,3 is a conjugated diene with the molecular formula C4H6. It has two double bonds, one between carbon atoms 1 and 2, and another between carbon atoms 3 and 4. - Butyne-1 is an alkyne with the molecular formula C4H6. It has a triple bond between carbon atoms 1 and 2. - Therefore, butadiene-1,3 and butyne-1 are isomers of each other.

3) Propene and butene: - Propene is an alkene with the molecular formula C3H6. It has a double bond between carbon atoms 1 and 2. - Butene is also an alkene with the molecular formula C4H8. It has a double bond between carbon atoms 1 and 2. - Therefore, propene and butene are not isomers of each other.

4) Hexane and 3-methylpent-1-yne: - Hexane is an alkane with the molecular formula C6H14. It consists of a straight chain of six carbon atoms with no double bonds or branches. - 3-methylpent-1-yne is an alkyne with the molecular formula C6H10. It has a triple bond between carbon atoms 1 and 2, and a methyl group attached to carbon atom 3. - Therefore, hexane and 3-methylpent-1-yne are isomers of each other.
