IUPAC Name of Isobutyl Bromide
The IUPAC name of isobutyl bromide is 1-bromo-2-methylpropane.
Explanation:
Isobutyl bromide is composed of four carbon atoms, ten hydrogen atoms, and one bromine atom. According to the IUPAC nomenclature rules, we should first identify the longest carbon chain, which in this case is a three-carbon chain. The carbon chain is numbered from the end closest to the bromine atom.
To name the compound, we follow the IUPAC naming rules in the following way:
1. Identify the longest carbon chain: It is a three-carbon chain.
2. Number the carbon chain: The carbon chain is numbered from the end closest to the bromine atom.
3. Name the substituent: The substituent is the bromine atom, which is named as bromo.
4. Assign the location of the substituent: The bromine atom is located at the first carbon atom. Therefore, it is named as 1-bromo.
5. Name the parent chain: The parent chain is a propane chain, which is named as propane.
6. Name the substituent: The substituent is the methyl group, which is named as methyl.
7. Assign the location of the substituent: The methyl group is located at the second carbon atom. Therefore, it is named as 2-methyl.
8. Combine the names: The IUPAC name of the compound is 1-bromo-2-methylpropane.
Thus, the correct option is D.
The IUPAC name of isobutyl bromide isa)1-bromo-3-methylbutaneb)3-bromo...
Explanation:
Isobutyl bromide is a compound with the molecular formula C4H9Br. The IUPAC name of isobutyl bromide is 1-bromo-2-methylpropane.
Reasoning:
To name the isobutyl bromide using IUPAC nomenclature, we need to identify the longest carbon chain containing the functional group, which is bromine in this case. The longest carbon chain in isobutyl bromide contains four carbon atoms, and it is a branched chain. The suffix for halogen-containing compounds is "-o" for bromine. Therefore, the name of the parent chain is butane, and the bromine atom is attached to the first carbon atom of the chain.
However, since the molecule is a branched chain, we need to indicate the position of the methyl group on the second carbon atom. The prefix for a branched chain is "iso-". Therefore, the name of the compound is 1-bromo-2-methylpropane.
Conclusion:
The correct IUPAC name of isobutyl bromide is 1-bromo-2-methylpropane.
