Question

Write the structures for all the isomers of the –C5H11 alkyl group.

Answer 1

The -C5H11 alkyl group has straight-chain and branched-chain isomers. The structures include 1-pentyl, 2-pentyl, 3-pentyl, 4-pentyl, 5-pentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 2,2-dimethylpropyl, and 2,3-dimethylbutyl.

Step-by-step explanation:

The -C5H11 alkyl group refers to a group of molecules with a molecular formula of C5H11. To write the structures of all the isomers, we need to determine the different ways we can arrange the carbon atoms in the molecule. For a C5 carbon chain, we can have straight-chain and branched-chain isomers.

1. Straight-chain isomers:

• 1-pentyl (all the carbon atoms are in a straight line)
• 2-pentyl (the pentyl group is attached to the second carbon atom)
• 3-pentyl (the pentyl group is attached to the third carbon atom)
• 4-pentyl (the pentyl group is attached to the fourth carbon atom)
• 5-pentyl (the pentyl group is attached to the fifth carbon atom)

2. Branched-chain isomers:

• 1-methylbutyl (3 carbon atoms in the main chain, 1 methyl group attached to the second carbon atom)
• 2-methylbutyl (3 carbon atoms in the main chain, 1 methyl group attached to the third carbon atom)
• 3-methylbutyl (3 carbon atoms in the main chain, 1 methyl group attached to the fourth carbon atom)
• 2,2-dimethylpropyl (3 carbon atoms in the main chain, 2 methyl groups attached to the second carbon atom)
• 2,3-dimethylbutyl (4 carbon atoms in the main chain, 2 methyl groups attached to the second and third carbon atoms)

These are the structures for all the isomers of the -C5H11 alkyl group.

Answer 2

Step-by-step explanation:

Alkyl groups are those which are derived from alkane by the removal of one hydrogen atom

For example ,methane CH4, and its corresponding alkyl groups is methyl -CH3
