Worked Solution & Example Answer:Oxidation of 4-methylpentan-2-ol to the corresponding ketone results in the alcohol A - Scottish Highers Chemistry - Question 9 - 2018
Step 1
Identifying the Process
Answer
To understand the oxidation of 4-methylpentan-2-ol to its corresponding ketone, we recognize that during oxidation, alcohols lose hydrogen atoms or gain oxygen, resulting in a weight change.
4-methylpentan-2-ol (C6H14O) contains one hydroxyl (-OH) group. Upon oxidation, this hydroxyl group converts to a carbonyl (C=O) group in the ketone form.
Step 2
Calculating Mass Change
Answer
To calculate the mass change during the oxidation from alcohol to ketone, we need to examine the molecular weights involved. The transition from an alcohol to a ketone involves the loss of 2 hydrogens (approximately 2 g) per mole of alcohol.
Thus:
- For each mole oxidized, the process loses about 2 g (due to the removal of 2 H atoms), leading to the production of the ketone.
