Interpretation: The name of the given compound is to be determined. The number of lines observed in its
Concept introduction:
Answer to Problem 20P
The IUPAC name of the given compound is
Explanation of Solution
The given molecule is
Figure 1
Black coloured atoms have four bonds. So, these are the carbon atoms. The grey coloured balls have one bond. So, these are the hydrogen atoms. The molecular structure of the compound is,
Figure 2
The parent name of the compound is benzene. The numbering will be in alphabetical order. Isopropyl group is present on first carbon atom and methyl group is present on fourth carbon atom. The IUPAC name of the given compound is
Thus, seven lines are present in
The IUPAC name of the given compound is
