But-2-ene has two geometrical isomers due to the presence of a double bond which restricts rotation. These isomers are:

1. cis-but-2-ene: In this isomer, the two methyl groups (-CH3) are on the same side of the double bond.

2. trans-but-2-ene: In this isomer, the two methyl groups (-CH3) are on opposite sides of the double bond.

Here's how you can draw them:

For cis-but-2-ene:
H H

C=C

H3C CH3

For trans-but-2-ene:
H3C H

Please note that the above structures are simplified and do not show the correct angles between bonds.
