Answer:
See attached picture.
Step-by-step explanation:
Hello,
In this case, for the required carboxylic acid, we should consider a central cyclohexane that at the first carbon has a carboxyl group COOH and at the fourth carbon has two chlorine radicals as shown on the attached picture. This type of compounds need to have the carboxyl group outside the ring in order to be considered as acids, otherwise the octet rule may not be respected for a cyclic carbon.
Regards.
