About Organic functional groups name typing
Read and type the names beside the Organic functional groups pictures. Practice 20 names in a fixed sequence, from Hydroxyl group to Phosphate monoester group, keeping each picture connected with its written term.
Connect 20 functional-group diagrams with names such as hydroxyl, carbonyl and amide.
R denotes the rest of the molecule. Compare bond orders and connectivity as well as element symbols; distinguish an amide from an amino group.
Enter the full displayed name or a registered alternative to advance automatically. You can edit unfinished text. Enter during input-method composition does not count as an error.
The first nonempty input starts the timer. The final screen shows elapsed time, keystrokes per minute and errors. Best times are stored in this browser separately for each topic, set and language.
How to play
- Choose a set from the selection page.
- Read the picture and current name together.

- A matching answer advances to the next name automatically.
- Review your results, retry or choose another set.
Who is it for?

Names and spelling
The displayed label is the representative name for that entry. Similar pictures can have different full names.
Only registered alternatives count as answers. Related terms in the explanation are not automatically accepted.
Changing the page language changes the names to type. Japanese pages include readings; Chinese pages include pinyin input.
Practice tips
- Read the current spelling before concentrating on speed.
- Break a long name into words, then type it as a whole.
- Enlarge the picture when comparing small features.
- Edit unfinished text directly. Enter on an incorrect nonempty answer records one error.
- Retry a set in the same fixed order.
- Switch to the corresponding page language to practice its names.

It starts with the first nonempty input, not while you read the list.
Where is my best time stored?
In this browser, separately by topic, set and language. Records are not automatically shared across devices.
