Question 1 · 1 mark · Difficulty 1/3

Which functional group is present in all carboxylic acids?

  1. -OH attached to a carbon chain
  2. -COO- attached to a carbon chain
  3. -CHO attached to a carbon chain
  4. -COOH attached to a carbon chain
Show answer & explanation
✓ Answer: D-COOH attached to a carbon chain
The carboxyl group, -COOH, defines carboxylic acids and consists of both a carbonyl (C=O) and a hydroxyl (-OH) group on the same carbon. Option A describes an alcohol functional group. Option C describes an aldehyde. Option D shows a carboxylate ion (the deprotonated form), not the neutral acid.
Question 2 · 1 mark · Difficulty 1/3

Propanoic acid and ethanol are heated together with a concentrated sulfuric acid catalyst. Which type of reaction is taking place?

  1. Neutralisation
  2. Esterification
  3. Oxidation
  4. Hydrolysis
Show answer & explanation
✓ Answer: BEsterification
Esterification is the reaction between a carboxylic acid and an alcohol (with an acid catalyst, typically concentrated H₂SO₄) to form an ester and water. Neutralisation involves an acid and a base producing a salt and water. Oxidation would convert an alcohol to an aldehyde, ketone, or acid. Hydrolysis breaks an ester down using water.

Edexcel GCSE Chemistry: Carboxylic acids: structure, properties and reactions FAQ

How many Edexcel GCSE Chemistry questions on Carboxylic acids: structure, properties and reactions are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Carboxylic acids: structure, properties and reactions for Edexcel GCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real Edexcel paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for Edexcel GCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Carboxylic acids: structure, properties and reactions practice with other Chemistry topics or even switch to a totally different Edexcel subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Carboxylic acids: structure, properties and reactions questions aligned to the official Edexcel GCSE Chemistry syllabus?
Every question is written against the published Edexcel GCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real Edexcel paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from Edexcel.
How is Carboxylic acids: structure, properties and reactions typically tested on Edexcel GCSE Chemistry papers?
Carboxylic acids: structure, properties and reactions appears across multiple question types on real Edexcel GCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
