Chapter 4: Q12P (page 150)

Draw the Z isomer of an alkene that has a CH3and an H on one sp2carbon and isopropyl and butyl groups on the othersp2carbon.

Short Answer

Expert verified

1. Assign the priority order to the groups on the basis of atomic number. The higher atomic number gets the highest priority.

2. If higher priority groups are on the same side, then it will be a Z isomer as shown below

3. If higher priority groups are on the different side, then it will be an E isomer as shown below.

Step by step solution

01

Steps to follow while drawing E and Z isomers.

1. Assign the priority order to the groups on the basis of atomic number. The higher atomic number gets the highest priority.

2. If higher priority groups are on the same side, then it will be a Z isomer as shown below

3. If higher priority groups are on the different side, then it will be an E isomer as shown below.

02

Step 2: The Z isomer of an alkene that has a  CH3 and an H on one sp2  carbon and isopropyl and butyl groups on the other  sp2  carbon.

Here the alkene is having a CH3 and H group on one side of the double bond and the isopropyl and butyl groups on the other side.
