Questions & Step-by-Step Solutions
What is the expected major product when 2-bromobutane undergoes elimination reaction?
Step 1: Identify the starting compound, which is 2-bromobutane. This compound has a bromine atom attached to the second carbon of a four-carbon chain.
Step 2: Understand that an elimination reaction involves the removal of a bromine atom and a hydrogen atom from adjacent carbons, leading to the formation of a double bond.
Step 3: Recognize that there are two possible positions for the double bond to form: between carbon 1 and carbon 2, or between carbon 2 and carbon 3.
Step 4: Determine the stability of the possible products. But-2-ene (double bond between carbon 2 and carbon 3) is more stable than But-1-ene (double bond between carbon 1 and carbon 2) because it is a more substituted alkene.
Step 5: Conclude that the major product of the elimination reaction of 2-bromobutane is But-2-ene due to its greater stability.
