A student names the second structure above 2,3-dimethylcyclohex-1-ene. What rule does thisviolate?
Interpretation:The rules violate by the student during naming of thegiven structure as 2, 3-dimethylcyclohex-1-ene needs to be determined.
Concept introduction:
The chemical name of the compound can be defined as the name of each element or sub-compounds which are present in the chemical composition of the compound.
Answer to Problem 1CTQ
The rule of branching in the ring is violated by the student. Therefore, the name of the compound is 1, 6-dimethylcyclohexane.
Explanation of Solution
The structure of the compound is given as −
The student named the above compound as 2, 3-dimethylcyclohex-1-ene. It is to be determined that the name given by the student is correct or not. Label all the carbon atoms which are present in the ring structure to determine that the name of the compound is correct or not. The parent chain is numbered in such a way to give the lowest possible number to the double bond and these two numbers will be placed before the suffix.
In the compound structure, the carbon with double bond should have lowest number because it has the greatest number of branches. Therefore, the numbering of the atom will start with the double bonded carbons which have methyl substituent.
Hence, the compound will be named as 1,6-dimethylcyclohexane. In this rule of the branching in a ring containing double bond is violated by the student.
Thus, the student violated the rule of branching in the ring. Hence the name of the structure is 1,6-dimethylcyclohexane.

- Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.arrow_forwardWe’ll see in the next chapter that there are two isomeric substances, both named 1,2-dimethylcyclohexane.

- Draw a stereoisomer of cis-1,2-dimethylcyclohexane. (Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.) • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • In cases where there is more than one answer, just draw one.
