Question

what are isomers? Give the isomers of hexane​

Answer 1

Answer:

Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. That excludes any different arrangements which are simply due to the molecule rotating as a whole, or rotating about particular bonds.

Explanation:

Hexane has five isomers:

• Hexane, CH3CH2CH2CH2CH2CH3, a straight chain of six carbon atoms.
• 2-Methylpentane (Isohexane), CH3CH(CH3)CH2CH2CH3, a five-carbon chain with one methyl branch on the second.
• 3-Methylpentane, CH3CH2CH(CH3)CH2CH3, a five-carbon chain with one methyl branch on the third.
• 2,3-Dimethylbutane, CH3CH(CH3)CH(CH3)CH3, a four-carbon chain with one methyl branch on the second and third.
• 2,2-Dimethylbutane (neohexane), CH3C(CH3)2CH2CH3, a four-carbon chain with two methyl branches on the second.
