Question

How many isomers are possible for the formula CH2CL2? Explain. draw each of them

Answer 1

There are two possible isomers for
`C_2H_2Cl_2`. Let's examine each one:

1. Cis-Isomer: In this arrangement, both chlorine atoms are attached to different carbon atoms, and they are on the same side of the molecule. It can be represented as:

H Cl

\ /

C=C

/ \

H Cl

2. Trans-Isomer: In this arrangement, both chlorine atoms are attached to the same carbon atom, and they are on opposite sides of the molecule. It can be represented as:

H Cl

\ /

C=C

/ \

Cl H

The formula
`C_2H_2Cl_2` represents a molecule that contains two carbon atoms, two hydrogen atoms, and two chlorine atoms. Isomers are molecules with the same molecular formula but different structural arrangements. To determine the number of possible isomers for
`C_2H_2Cl_2`, we need to consider the different ways the atoms can be arranged.

In this case, there are two possible isomers for
`C_2H_2Cl_2`. Let's examine each one:

1. Cis-Isomer: In this arrangement, both chlorine atoms are attached to different carbon atoms, and they are on the same side of the molecule. It can be represented as:

H Cl

\ /

C=C

/ \

H Cl

2. Trans-Isomer: In this arrangement, both chlorine atoms are attached to the same carbon atom, and they are on opposite sides of the molecule. It can be represented as:

H Cl

\ /

C=C

/ \

Cl H

These two isomers represent the different ways the atoms can be arranged for the formula
`C_2H_2Cl_2`.
