C. 1, 4–dimethyl–1–cyclohexene
D. 4, 6–dichloro–1–heptene
Explanation:
C. Determination of the name of the compound.
To name the compound given above we must observe the following:
1. Determine the functional group of the compound. In this case, the functional group is the double bond (–C=C–).
2. Determine the parent name by counting the number of carbon that makes up the ring. In this case, 6 carbon makes up the ring. Hence the parent name is cyclohexene.
3. Identify the substituent group attached to the compound. In this case, two methyl group i.e –CH₃ are attached.
4. Locate the position of the substituent group attached by giving the functional group the lowest possible count. In this case, the functional group is at carbon 1, the first methyl group is at carbon 1 and the 2nd methyl group is at carbon 4.
5. Combine the above to obtain the name. Thus, the name of the compound is:
1, 4–dimethyl–1–cyclohexene.
D. Determination of the name of the compound.
To name the compound given above we must observe the following:
1. Determine the functional group of the compound. In this case, the functional group is the double bond (–C=C–).
2. Determine the parent name by counting the number of carbon that makes up the chain. In this case, 7 carbons makes up the chain. Hence, the parent name of the compound is heptene.
3. Identify the substituent group attached to the compound. In this case, two chlorine (Chloro) i.e –Cl are attached.
4. Locate the position of the substituent group attached by giving the functional group the lowest possible count. In this case, the functional group is at carbon 1, the first chlorine is at carbon 4 and the 2nd is at carbon 6.
5. Combine the above to obtain the name. Thus, the name of the compound is:
4, 6–dichloro–1–heptene
