Question

Draw the cis and trans forms for each of the following:

a) $2-$Butene

b) $2-$hexene

Short answer

The cis and trans forms are:

a)

b)

Step-by-step solution

Part (a) Step 1: Given information

We have to draw the cis and trans forms of$2-$butene.

Part (a) Step 2: Explanation:

The cis form is:

Cis isomers are molecules that have the same atom connectivity. On the same side of a double bond, they have comparable side groups.

The trans form is:

Molecules with similar side groups on opposing sides of a double bond are called trans isomers.

Part(b) Step 1: Given information

We have to draw cis and trans forms for$2-$hexene.

Part (b) Step 2: explanation

The cis form is:

Cis isomers are molecules that have the same atom connectivity. On the same side of a double bond, they have comparable side groups.

The trans form is:

Molecules with similar side groups on opposing sides of a double bond are called trans isomers.
