Question 28
How many structural isomers with the molecular formula C3H8O react with Tollens' reagent?
Worked Solution & Example Answer:How many structural isomers with the molecular formula C3H8O react with Tollens' reagent? - AQA - A-Level Chemistry - Question 28 - 2018 - Paper 3
Step 1
Identify Isomers
Answer
The molecular formula C3H8O can yield several structural isomers. In this case, we need to focus on isomers that contain either an aldehyde or a ketone, as these will react with Tollens' reagent.
For C3H8O, the structural isomers include:
- Propan-1-ol (1 propanol)
- Propan-2-ol (2 propanol)
- Ethyl methyl ether
- Acetone (propan-2-one) (Note that we will not consider this, as it does not have an aldehyde group.)
- Acetaldehyde (Ethanal)
Only Propan-1-ol and Acetaldehyde (Ethanal) will react with Tollens' reagent.
