a.
Interpretation:The given compound is to be named.
Concept Introduction: The naming of carbon compounds is done according to IUPAC principles.
a.

Answer to Problem 6RQ
The name of the given compound is 1,2-dimethylbenzene.
Explanation of Solution
The main carbon group is benzene. The two methyl groups are attached on the first and second carbon which adds the 1,2-dimethyl- prefix.
b.

Concept Introduction: The naming of carbon compounds is done according to IUPAC principles.
b.

Answer to Problem 6RQ
The name of the given compound is 1,3,5-tribromobenzene.
Explanation of Solution
The main carbon group is benzene. The three bromo groups are attached to the first, third and fifth carbon which gives the 1,3,5-tribromo- prefix.
d.
