Question

These are the structures of cis and trans isomers for 1-ethyl-3-methylcyclobutane.

trans-1-ethyl-3-methylcyclobutane

cis-1-ethyl-3-methylcyclobutane

By definition of cis and trans isomerism , the substituent groups when oriented in the same direction constitute the cis isomer and when oriented in the opposite direction constitute the trans isomer.

The isomers are visualized in chemistry by Wedge-dash notation . The cis isomer is represented by showing both the substituent groups with wedge (coming towards you from the plane of the screen) and the trans isomer is represented by showing one substituent with a wedge and another with dash (going away from you from the plane of the screen )

undefined To draw the cis and trans isomers for 1-ethyl-3-methylcyclobutane, first draw the cyclobutane ring with one methyl group and one ethyl group attached at carbon atoms 1 and 3, respectively. For the cis isomer, position the methyl and ethyl groups on the same side of the ring, while for the trans isomer, position them on opposite sides of the ring.
