Questions & Step-by-Step Solutions
Which of the following pairs of compounds are geometric isomers?
Step 1: Understand what geometric isomers are. They are compounds that have the same molecular formula but differ in the arrangement of atoms around a double bond.
Step 2: Identify the compounds given in the question. In this case, we have cis-2-butene and trans-2-butene.
Step 3: Look at the structure of cis-2-butene. In this compound, the two methyl groups (CH3) are on the same side of the double bond.
Step 4: Now, look at the structure of trans-2-butene. Here, the two methyl groups (CH3) are on opposite sides of the double bond.
Step 5: Compare the two structures. Since they have the same molecular formula (C4H8) but different arrangements around the double bond, they are geometric isomers.
