Concept introduction:
Rules for writing IUPAC name from the structural formula are given below.
• First, identify the longest carbon chain.
• The next step is to identify the groups attached to the longest chain.
• Identify the position, location, and a number of the substituents bonded to the carbon chain.
• Use prefix di, tri, tetra if the same type of substituents are present.
• Name the substituents in alphabetical order.
Answer to Problem 4.46AP
The correct IUPAC name of
Explanation of Solution
When a compound is named the first thing is to identify the longest parent chain. If the parent chain is substituted, then it is numbered in such a manner so that the substituent gets the lowest locant number. In the given case, the structure is written as shown below.
Figure 1
The method of numbering the parent chain is wrong because it is substituted by a double bond. It has to be numbered in such a way so that double bond gets the lowest locant number. The lowest locant number is

Explanation of Solution
When a compound is named the first thing is to identify the longest parent chain. If the parent chain is substituted, then it is numbered in such a manner so that the substituent gets the lowest locant number. In the given case, structure and numbering is written as shown below.
Figure 5
The method of numbering the parent chain is wrong because it is substituted by a double bond and a methyl group. It has to be numbered in such a way so that double bond and methyl group gets the lowest locant number. The lowest locant number for the double bond is
