What is it?
NaBH4 alcohol. Acid + alcohol ester. 1 alcohol reflux acid. Hydration of ethene to ethanol sits next door. Name: propanal vs propanone locant and suffix. This page separates the idea from the wider topic “EXAM RESPONSE (CARBONYLS AND ACIDS)” so it can be revised and assessed on its own.
In simple words
- NaBH4 alcohol.
- Ethanal -> ethanol
- Exam link: names of reagents.
Important terms
CONVERSIONS: NaBH4 alcohol.
EXAM RESPONSE (CARBONYLS AND ACIDS): Typical tasks: al vs ketone tests; DNPH then Tollens; iodoform on propanone; carbonate fizz; esterification; reduction products.
What you should learn
- Define conversions using accurate chemistry terms.
- Explain why conversions matters within exam response (carbonyls and acids).
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Examples
- Ethanal -> ethanol
- Ethanoic + ethanol ester
- No drug routes
KEY IDEA
NaBH4 alcohol. Acid + alcohol ester. 1 alcohol reflux acid. Hydration of ethene to ethanol sits next door. Name: propanal vs propanone locant and suffix.
EXAM APPLICATION
Worked 4-mark unknown C3H6O: DNPH ppt: carbonyl Tollens no: ketone iodoform yes: propanone not propanal State that ketones cannot be oxidised by mild agents — reason for Fehling negative.
Recommended for Class 11

Common exam traps
- Do not treat conversions as the same as every other part of exam response (carbonyls and acids); define this unit and use its own evidence, steps, or conditions.
- Do not memorise a label alone; connect the definition to a process, structure, condition, equation, or example.
