Questions: Chapter 2 Quiz Question 2 of 8 (1 point) Question Attempt: 1 of 1 Draw the bond-line (skeletal) formula of a compound with the molecular formula C5H10Br2 that meets the specified condition. Part 1 of 2 All of the carbon atoms belong to methylene (-CH2-) groups.

Solution Steps

To meet the condition that all carbon atoms belong to methylene (\(-\mathrm{CH}_{2}-\)) groups, we need to arrange the carbon atoms in such a way that each carbon is bonded to two hydrogen atoms and two other groups.

Given the molecular formula \(\mathrm{C}_{5} \mathrm{H}_{10} \mathrm{Br}_{2}\), we need a five-carbon chain where each carbon is part of a methylene group. This implies a straight chain of five carbons.

To satisfy the molecular formula, we need to add two bromine atoms to the structure. Since each carbon is a methylene group, we can place the bromine atoms on any two different carbons in the chain.

The bond-line (skeletal) formula for the compound can be drawn as follows:

\[ \mathrm{Br}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{Br} \]

This structure ensures that all carbon atoms are part of methylene groups and the molecular formula \(\mathrm{C}_{5} \mathrm{H}_{10} \mathrm{Br}_{2}\) is satisfied.
