What is the High School Organic Chemistry Quiz?
The High School Organic Chemistry Quiz is a free 4-choice web app for reviewing organic chemistry topics such as functional groups, isomers, alcohols, carbonyl compounds, carboxylic acids, esters, aromatic compounds, reactions, and identification questions.
All quiz questions, choices, explanations, and diagrams in this app are original practice materials created for this site. They are not copied from textbooks, workbooks, entrance examinations, mock examinations, school handouts, official PDFs, or publisher materials.

Practice topics for long-tail organic chemistry searches
This quiz is useful when you want to review phrases such as functional group identification, structural isomer counting, alcohol and ether classification, aldehyde and ketone comparison, carboxylic acid and ester reactions, benzene derivatives, phenol, aniline, benzoic acid, and organic compound identification.
The questions are intentionally short and original, so they can be used for quick review before school tests, basic entrance-exam preparation, or repeated practice of weak topics without reproducing any specific textbook or exam sequence.
How to use this quiz for review
First, choose a focused course such as Functional Groups, Isomers, or Aromatic Compounds. After answering, open the hint to check which structural feature or observation led to the answer.
For reaction and identification questions, pay attention to the starting functional group, the condition, the observation, and the product. The app emphasizes reasoning rather than memorizing a copied problem pattern.
