Question 5
How many isomers are there for C3H6Cl2? (A) 3 (B) 4 (C) 5 (D) 6
Worked Solution & Example Answer:How many isomers are there for C3H6Cl2? (A) 3 (B) 4 (C) 5 (D) 6 - HSC - SSCE Chemistry - Question 5 - 2006 - Paper 1
Step 1
Identify possible structural isomers
Answer
For the compound C3H6Cl2, we start by considering both the positions of the chlorine atoms and the structure of the carbon skeleton. The molecular formula indicates that we have a three-carbon chain with two chlorine substituents. The isomers can be categorized based on whether the chlorines are on the same carbon or on different carbons.
Step 2
Count distinct isomers
Answer
- 1,1-Dichloropropane: Both chlorines are on the first carbon.
- 1,2-Dichloropropane: One chlorine on the first carbon and one on the second carbon.
- 1,3-Dichloropropane: One chlorine on the first carbon and one on the third carbon.
After considering these arrangements, we find a total of three distinct isomers.
