Question: Which of the following is the correct stereochemical configuration for 2-butene?

Options:

Correct Answer: both cis and trans

Solution:

2-butene can exist as both cis and trans isomers due to the presence of a double bond between the second and third carbons.

Which of the following is the correct stereochemical configuration for 2-butene?

Which of the following is the correct stereochemical configuration for 2-butene?

Step 1: Understand that 2-butene is a type of alkene, which means it has a double bond.
Step 2: Identify the structure of 2-butene, which has four carbon atoms (C4) and a double bond between the second and third carbon atoms.
Step 3: Recognize that the double bond can create different arrangements of the atoms around it.
Step 4: Learn that these different arrangements are called isomers, specifically cis and trans isomers.
Step 5: In the cis isomer, the two methyl groups (CH3) are on the same side of the double bond.
Step 6: In the trans isomer, the two methyl groups are on opposite sides of the double bond.
Step 7: Conclude that 2-butene can exist in both cis and trans forms due to the double bond.
