Q
Q: What is the stereochemical outcome of the addition of H2 across an alkene?
Solution:
The addition of H2 across an alkene occurs via syn addition, resulting in both hydrogens adding to the same side of the double bond.
Steps: 5
Show Steps
Step 1: Understand that an alkene is a molecule with a double bond between two carbon atoms.
Step 2: Know that adding H2 means we are adding two hydrogen atoms to the alkene.
Step 3: Recognize that the addition of H2 happens in a specific way called 'syn addition'.
Step 4: In syn addition, both hydrogen atoms attach to the same side of the double bond.
Step 5: This results in a new molecule where the double bond is replaced by a single bond, and both hydrogens are on the same side.
