Structural Isomers of C₄H₈Br₂: Exciting Chemistry Exploration!

How many structural isomers are there of molecular formula C₄H₈Br₂ with branched carbon chains?

What are the names and graphical formulae of two of the branched chain isomers of C₄H₈Br₂?

Answer:

There are nine structural isomers of molecular formula C₄H₈Br₂, three of which have branched carbon chains. Two of the branched chain isomers are:

1. Isomer 1: 2-bromo-1-bromomethylpropane

2. Isomer 2: 1-Bromo-2-bromomethylpropane

Chemistry enthusiasts, get ready to dive into the fascinating world of structural isomers! The molecular formula C₄H₈Br₂ offers a plethora of possibilities, including branched chain isomers.

1. 2-bromo-1-bromomethylpropane:

In this isomer, one bromine atom is attached to the second carbon of the main chain, while the other bromine atom is connected to an attached methyl group. Visualize a four-carbon chain with an additional -CH2Br group attached to one of the middle carbons. The graphical formula depicts this unique arrangement.

2. 1-Bromo-2-bromomethylpropane:

For this exciting branched isomer, one bromine atom is linked to the first carbon of the main chain, and the other bromine atom is attached to a methyl group on the second carbon. Imagine a four-carbon chain with an extra -CH2Br attached to the second carbon. The graphical formula brings this intriguing structure to life.
