Questions & Step-by-Step Solutions
What type of isomerism is exhibited by 1-butene and cis-2-butene?
Step 1: Understand what isomerism means. Isomerism is when two or more compounds have the same formula but different structures.
Step 2: Identify the compounds in the question. We have 1-butene and cis-2-butene.
Step 3: Look at the structure of 1-butene. It has a double bond between the first and second carbon atoms.
Step 4: Look at the structure of cis-2-butene. It has a double bond between the second and third carbon atoms, with two methyl groups on the same side.
Step 5: Recognize that the difference in arrangement around the double bond is what makes them different. 1-butene has a different arrangement than cis-2-butene.
Step 6: Conclude that since the difference is in the spatial arrangement around the double bond, they are geometric isomers.
