ChemistryChapter 19: Carbonyl Compounds
Exam Response (carbonyls and Acids) — Conversions
NaBH4 alcohol. Acid + alcohol ester.
Learning objectives
- 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.
Definition
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.
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.
Overview
Study this learning unit in three steps:
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.
Examples Ethanal -> ethanol · Ethanoic + ethanol ester · No drug routes
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.
Examples Ethanal -> ethanol · Ethanoic + ethanol ester · No drug routes
WHAT — EXAM RESPONSE (CARBONYLS AND ACIDS) — CONVERSIONS
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.
WHY — Why this topic matters
EXAM RESPONSE (CARBONYLS AND ACIDS) — CONVERSIONS is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
NaBH4 alcohol. Acid + alcohol ester. 1 alcohol reflux acid. Hydration of ethene to ethanol sits next door. Name: propanal vs propanone locant and suffix. Examples: Ethanal -> ethanol; Ethanoic + ethanol ester; No drug routes. Exam use: 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.

Common misconception
- 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.
FBISE exam check
- Define exam response (carbonyls and acids) — conversions, explain how it works, and support the answer with one relevant example.
60-second revision
- NaBH4 alcohol.
- Ethanal -> ethanol
- Exam link: names of reagents.
