Concept explainers
(a)
Interpretation:
1,3-dimethylcyclopentane showing cis-trans isomerism to be identified.
Concept Introduction:
For getting cis trans isomerism atleast two substituent need to be attached with the parent cyclic chain of carbon.
The cis isomer indicates the position of substituent on same plane.
The trans isomer indicates the position of substituent are on opposite plane.
(b)
Interpretation:
Ethylcyclopentane showing cis-trans isomerism to be identified.
Concept Introduction:
For getting cis trans isomerism atleast two substituent need to be attached with the parent cyclic chain of carbon.
The cis isomer indicates the position of substituent on same plane.
The trans isomer indicates the position of substituent are on opposite plane.
(c)
Interpretation:
1,3- dimethylcyclohexane showing cis-trans isomerism to be identified.
Concept Introduction:
For getting cis trans isomerism atleast two substituent need to be attached with the parent cyclic chain of carbon.
The cis isomer indicates the position of substituent on same plane.
The trans isomer indicates the position of substituent are on opposite plane.
