If chlorocyclohexane is subjected to further chlorination, how many different isomers (geometrical plus structural only) of dichiorocyclohexane would be produced?a)3b)5c)6d)7Correct answer is option 'D'. Can you explain this answer?

Question

Accepted Answer

The correct answer is option D
There will be three constitutional isomers i.e. 1,2 dichloro cyclohexane,1,3 dichloro cyclohexane and1,4 dichloro cyclohexane.Each constitutional isomer will have cis and trans configuration thereby making six isomers in all.Also there will be two optically active isomers.

1,2 dichloro cyclohexane

Answer

Answer

1,2dichlorohexane;1,3dichlorohexane;1,4dichlorohexane nd their geometrical isomers=6 and then 1,1dichlorohexane is a structural isomer of all the above isomer.so the total geometrical plus structural isomers are 7

Answer

Answer

Different Isomers of Dichlorocyclohexane
Dichlorocyclohexane is an organic compound that is derived from cyclohexane by replacing two hydrogen atoms with chlorine atoms. To determine the number of different isomers of dichlorocyclohexane that can be produced from chlorocyclohexane, we need to consider both structural and geometrical isomerism.

1. Structural Isomerism:
Structural isomers have the same molecular formula but differ in the arrangement of atoms. In the case of dichlorocyclohexane, we can have different structural isomers depending on the position of the two chlorine atoms on the cyclohexane ring. Let's consider the possible positions:

a) 1,2-Dichlorocyclohexane: Chlorine atoms are attached to carbon atoms 1 and 2.
b) 1,3-Dichlorocyclohexane: Chlorine atoms are attached to carbon atoms 1 and 3.
c) 1,4-Dichlorocyclohexane: Chlorine atoms are attached to carbon atoms 1 and 4.
d) 1,5-Dichlorocyclohexane: Chlorine atoms are attached to carbon atoms 1 and 5.
e) 1,6-Dichlorocyclohexane: Chlorine atoms are attached to carbon atoms 1 and 6.
f) 1,4-Dichlorocyclohexane (different ring position): Chlorine atoms are attached to carbon atoms 2 and 3.

So, considering the different possible positions of the chlorine atoms, we have a total of 6 different structural isomers of dichlorocyclohexane.

2. Geometrical Isomerism:
Geometrical isomers arise when there is restricted rotation around a bond, leading to different spatial arrangements. However, in the case of dichlorocyclohexane, there is no possibility of geometrical isomerism because the two chlorine atoms are attached to the same carbon atom in all the structural isomers mentioned above.

Therefore, the total number of different isomers (geometrical plus structural) of dichlorocyclohexane would be 6 (as determined from structural isomerism only).

Hence, the correct answer is option D) 7.
