Structure:
The given compound is 2,3-dimethylpentane. Let's break down the structure to understand it better:
Branch 1: CH3 CH(CH3)
This branch is a 2-methylpropane group. It consists of a central carbon (C) bonded to three hydrogen atoms (H) and a methyl group (CH3) attached to one of the carbon's three available bonds.
Branch 2: C(CH3) C(CH2 CH3)
This branch is a 3-methylbutane group. It consists of a central carbon (C) bonded to three hydrogen atoms (H) and two methyl groups (CH3) attached to the carbon's two remaining available bonds.
Overall Structure:
The overall structure of the compound is formed by twice repeating the main chain, which is C(CH3 CH2)C(CH3). This main chain consists of a central carbon (C) bonded to two hydrogen atoms (H) and two alkyl groups. The alkyl groups are a methyl group (CH3) and an ethyl group (CH2 CH3).
Explanation:
The compound 2,3-dimethylpentane consists of two branches. Let's analyze each branch individually:
Branch 1: CH3 CH(CH3)
- The central carbon (C) in this branch is bonded to three hydrogen atoms (H) and a methyl group (CH3).
- It is called a 2-methylpropane group because the methyl group is attached to the second carbon atom in the chain.
- The presence of the methyl group causes branching in the structure.
Branch 2: C(CH3) C(CH2 CH3)
- The central carbon (C) in this branch is bonded to three hydrogen atoms (H) and two methyl groups (CH3).
- It is called a 3-methylbutane group because the two methyl groups are attached to the third carbon atom in the chain.
- The presence of the two methyl groups causes branching in the structure.
Overall Structure:
The overall structure of the compound is formed by repeating the main chain, which is C(CH3 CH2)C(CH3), twice. This main chain consists of a central carbon (C) bonded to two hydrogen atoms (H) and two alkyl groups. The alkyl groups are a methyl group (CH3) and an ethyl group (CH2 CH3).
The repetition of the main chain is indicated by "twice" in the compound name, 2,3-dimethylpentane.
The compound has a total of 11 carbon atoms, 24 hydrogen atoms, and no functional groups.
