Question

cis isomer
and trans isomer
​

Answer 1

Answer:

Explanation:

Now as you have not asked anything particular about the question, i assume you know nothing bout the terms. So here is a bit general info about them.

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in organic chemistry.

Cis-trans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are rotated into a different orientation in three-dimensional space.

When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas, when the substituents are oriented in opposing directions, the diastereomer is referred to as trans. An example of a small hydrocarbon displaying cis–trans isomerism is pentene.

Answer 2

Answer:

The  organic compound having the same molecular formula but different structures are called isomers

Explanation:

Cis–trans isomerism

Cis isomers are molecules with the same connectivity of atoms. They feature same side groups placed on the same side of a double bond. Trans isomers feature molecules with same side groups placed on opposite sides of a double bond

• If the two substituents are on the same side of the double bond, the configuration of the bond is cis. If the two substituents are on opposite sides of the double bond, the configuration of the bond is trans.
• An example of a small hydrocarbon displaying cis–trans isomerism is but-2-ene.
