Answer #1

1. answer is option a. 2 unique structure

explanation: in trans isomer one substitutent will have up bond and other substitutent will have down bond, trans compound will have two unique structure as shown below

2. answer is option d. 2 unique structure

explanation: in cis isomer both substitutent will have two up bond or down bond, cis compound will have two unique structure as shown below

3. answer is option a. 1 unique structure

explanation: trans 1,4 cyclohexane is meso compound that it has internal plane of symmetry, therefore only one unique structure is possible

4. The answer is option b: 1 unique structure

explanation: cis 1,4 cyclohexane is meso compound that it has internal plane of symmetry, therefore only one unique structure is possible

5. The answer is option c. there are 2 unique structure

explanation: in cis isomer both substitutent will have two up bond or down bond, cis compound will have two unique structure as shown below

6. answer is option b. There are more than 4 unique structure

Explanation: only one unique structure only possible
