Give the iupac name for the following structure: 3-chloro-6-methylcyclohexanol 2-methyl-5-chlorocyclohexanol 1-chloro-4-methylcyclohexanol 5-chloro-2-methylcyclohexanol 2-methyl-3-chlorocyclohexanol

5-chloro-2-methylcyclohexanol    

Explanation:  

There is no structure for the compound, but we can analyze the proposed options using the IUPAC rules to name organic compounds.  

IUPAC rules state that to name an organic compound, first we have to identify the priorities for the functional groups present in the compound. In this case, the priority functional group is the alcohol group, so we will start the counting of the carbons in this group. Then, the counting of carbon atoms is followed by the next substituents so they have the lowest possible numbers, in this case, we can assign the number 2 to the methyl group and 5 to the chloride group, and name the compound in alphabetical order, using commas to separate the words from the numbers and with no space between the words.                      

Since the other options involve: high countings for the susbtituents groups  (3-chloro-6-methylcyclohexanol), wrong assignation of priority functional group (1-chloro-4-methylcyclohexanol), wrong sequence of counting in the compound (2-methyl-3-chlorocyclohexanol) and no alphabetical order to name the compound (2-methyl-5-chlorocyclohexanol), the correct option is:            

5-chloro-2-methylcyclohexanol  

Have a nice day!
