Discuss the anticipated stereochemistry of each of the following compounds.
a.`BrCH=C=C=CHBr`
b. `CH_(2)=C=C=CHBr`
c. `BrCH=C=C=CBr_(2)`

Explanation

To discuss the anticipated stereochemistry of the given compounds, we will analyze each compound based on the number of double bonds and their arrangement.

### a. `BrCH=C=C=CHBr`

1. **Identify the Structure**: The compound has two bromine atoms attached to the terminal carbons and three double bonds in total.

2. **Count the Double Bonds**: There are four carbon atoms connected by three double bonds. The presence of three double bonds (an odd number) suggests that the compound is planar.
