Answer:
<span>A geometric isomer with two alkyl groups on the same side of the carbon-carbon double bond is called <em>cis</em> Isomer.
Explanation:
Geometric isomerism takes place about the double bond in alkenes when the alkyl groups are either situated at the same side (<em>cis</em>) or are situated opposite (<em>trans</em>) to each other.
Example:
<em>cis</em>-2-Butene (highlighted red)
<em>trans</em>-2-Butene (highlighted blue)</span>
