Text Solution

AI Generated Solution

To determine whether 1-bromobutane and 1-bromo-2-methylpropane are chain isomers, we can follow these steps: ### Step 1: Identify the Chemical Formula of Each Compound 1. **1-bromobutane**: The structure consists of a straight chain of four carbon atoms (butane) with a bromine atom attached to the first carbon. The chemical formula is C4H9Br. 2. **1-bromo-2-methylpropane**: This compound has a three-carbon propane chain with a methyl group (–CH3) attached to the second carbon and a bromine atom on the first carbon. The chemical formula is also C4H9Br. ### Step 2: Compare the Chemical Formulas Both compounds have the same chemical formula: C4H9Br. This is a necessary condition for them to be considered isomers. ...
