Question

what are geometric isomers?
compounds that have the same atoms arranged in the same order, but with different three - dimensional orientations
compounds that have the same atoms arranged in the same order, and have the same three - dimensional orientations

Explanation:

Geometric isomers are a type of isomerism in chemistry. Isomers are compounds with the same molecular formula. Geometric isomers specifically have the same atoms arranged in the same order (same connectivity), but differ in their three - dimensional orientations. This is often due to restricted rotation around a bond (such as a double bond in organic chemistry). For example, in alkenes like but - 2 - ene, there are cis and trans isomers. In the cis isomer, the similar groups (e.g., two methyl groups) are on the same side of the double bond, while in the trans isomer, they are on opposite sides.
