Question

Antiseptic chloroxylenol is:
a.) 4-chloro-3, 5-dimethyl phenol
b.) 3-chloro-4, 5-dimethyl phenol
c.) 4-chloro-2, 5-dimethyl phenol
d.) 5-chloro-3, 4-dimethyl phenol

Answer 1

Hint: To answer the correct option, we should know about antiseptic chloroxylenol. We should know the proper structure to give the correct IUPAC name.


Complete step by step solution:
We should first know about chloroxylenol. We should know that it is an antiseptic and disinfectant which is used for skin disinfection and cleaning surgical instruments. We also use it as disinfectants and wound cleaners. This compound is used in our house for cleaning purposes. We should know that it is less effective than some other available cleaners.
Now, we will draw the structure of this compound and then we will name it.

The above structure is chloroxylenol. As we observe the structure, we can easily answer the IUPAC name of the above structure. By looking at the structure, we can say that the other name of chloroxylenol is para-chloro-meta-xylenol (PCMX). And we can say that its IUPAC name is 4-Chloro-3, 5-dimethylphenol.
From this we can say that option A is the correct answer.

Note: We should note that its chemical formula is\[{{\text{C}}_{\text{8}}}{{\text{H}}_{\text{9}}}\text{ClO}\]. We should know about its toxicity. We should know that chloroxylenol is not significantly toxic to humans, is practically non-toxic to birds, and is moderately toxic to freshwater invertebrates. It is highly toxic to fish, cats, and some amphibians and should not be used around them.
