Worked Solution & Example Answer:A compound with molecular formula C₆H₁₂O₂ could be A - Scottish Highers Chemistry - Question 7 - 2019
Step 1
Identify the correct compound from the options
Answer
To find the correct compound with the molecular formula C₆H₁₂O₂, we need to analyze each option based on its structure and corresponding formula:
- Pentyl ethanoate: This compound is an ester and its formula is C₇H₁₄O₂ (C₅H₁₁COOCH₃), which does not match C₆H₁₂O₂.
- Hexan-2-one: This is a ketone with the formula C₆H₁₂O (C₆H₁₂=O), which again does not match C₆H₁₂O₂.
- 3-methylpentan-2-ol: This is an alcohol with the formula C₇H₁₄O (C₅H₁₁CH(OH)CH₃), which also does not fit.
- Hexanoic acid: This compound is a carboxylic acid and its formula is precisely C₆H₁₂O₂ (C₆H₁₁COOH).
Through this analysis, hexanoic acid is the only option with the correct molecular formula C₆H₁₂O₂.
