Answer: Option (b) is the correct answer.
Explanation:
A geometric isomer is defined as an isomer that contains different arrangement of groups across the double bond, ring etc. Generally, coordination compounds show geometric isomers.
For example, cis-2,butene and trans-2,butene are geometrical isomers.
Geometrical isomers cause change in geometry of a compound. Due to this both physical and chemical properties of a substance changes.
On the other hand, structural isomers are the isomers that have same chemical formula but different structure due to different sequence of atoms present in the formula.
For example, butane and isobutane are structural isomers.
Therefore, we can conclude that geometric isomers only have different physical or chemical properties. ty
