IUPAC Name: 2-propylpent-1-ene

Answer 2

Answer : The IUPAC name of the given compound is, 2-propylpent-1-ene

Explanation :

The basic rules for naming alkene are :

1. The longest possible carbon chain should include the carbons of double bond.
2. The longest chain is given the name by replacing suffix -ane with -ene.
3. The numbering is done in such a way that first carbon of double bond gets the lowest number.
4. The carbon atoms of the double bond get the preference over the other substituents present in the parent chain.
5. The position of double bond is indicated by placing the number before the suffix -ene.
6. If more than one double bond is present then the location of each double bond is indicated just before the suffix and the suffix used for two double bonds is -diene, for three double bonds is -triene and so on.

Thus the IUPAC name of the given compound is, 2-propylpent-1-ene.

The structure of the given compound are shown below.
