Worked Solution & Example Answer:Which of the following carbon containing compounds is an isomer of hexanal? A 2-methylbutanal B 3-methylpentan-2-one C 2,2-dimethylbutan-1-ol D 3,3-dimethylpentanal - Scottish Highers Chemistry - Question 10 - 2023
Step 1
Step 2
Evaluate each compound for isomerism
Answer
An isomer contains the same molecular formula but a different structure. The molecular formula of hexanal is C₆H₁₂O.
- A. 2-methylbutanal: Structure: C₅H₈O (isomer, as it has 5 carbons).
- B. 3-methylpentan-2-one: Structure: C₆H₁₂O (same molecular formula, so it can be an isomer).
- C. 2,2-dimethylbutan-1-ol: Structure: C₆H₁₄O (not an isomer, as the molecular formula differs).
- D. 3,3-dimethylpentanal: Structure: C₇H₁₄O (not an isomer, as it has 7 carbons).
Upon evaluation, only option B has the same molecular formula as hexanal, making it an isomer.
