Current Question (ID: 21237)

Question:

$\text{The correct IUPAC name of the following compound is:}$ $\begin{array}{c} \text{NO}_2 \\ \text{Cl} \\ \text{CH}_3 \end{array}$

Options:

1. $5\text{-Chloro-4-methyl-1-nitrobenzene}$
2. $2\text{-Chloro-1-methyl-4-nitrobenzene}$
3. $2\text{-Methyl-5-nitro-1-chlorobenzene}$
4. $3\text{-Chloro-4-methyl-1-nitrobenzene}$

Solution:

$\text{Hint: Follow lowest sum rule}$ $\text{Step 1:}$ $\text{The given compound is as follows:}$ $\begin{array}{c} \text{NO}_2 \\ \text{Cl} \\ \text{CH}_3 \end{array}$ $\text{In the given compound, no group gets higher priority, just numbering the benzene ring in such a way that, the lowest sum is obtained. The possible numbering system is as follows:}$ $\text{Sum} = 1+3+4 = 8$ $\text{Sum} = 1+2+5 = 8$ $\text{Sum} = 1+2+4 = 7$ $\text{Step 2:}$ $\text{The lowest sum is 7. Thus, that numbering system is used.}$ $\begin{array}{c} \text{NO}_2 \\ \text{Cl} \\ \text{CH}_3 \end{array}$ $\text{Hence, the IUPAC name of the compound is 2-Chloro-1-methyl-4-nitrobenzene}$
