Q: How many stereoisomers does 1,2-dichloropropane have?
Solution: 1,2-dichloropropane has one chiral center, leading to 2 stereoisomers.
Steps: 6
Step 1: Identify the structure of 1,2-dichloropropane. It has three carbon atoms (propane) and two chlorine atoms attached to the first and second carbon.
Step 2: Determine if there are any chiral centers. A chiral center is a carbon atom that has four different groups attached to it.
Step 3: Look at the first carbon (C1) with a chlorine atom, a hydrogen atom, and a carbon chain. It has two identical groups (the other carbon), so it is not chiral.
Step 4: Look at the second carbon (C2) with a chlorine atom, a hydrogen atom, and a carbon chain. It also has two identical groups (the other carbon), so it is not chiral.
Step 5: Since there is one chiral center (C2), it can exist in two different configurations (R and S).
Step 6: Therefore, 1,2-dichloropropane has 2 stereoisomers.
