One-Minute Recognition Table Functional Groups

A set of flashcards for recognizing organic functional groups by their patterns and chemical descriptions based on the lecture recognition table.

Alcohol

$OH$ (Oxygen + Hydrogen)

Aldehyde

$CHO$ (Carbonyl + H)

Ketone

$COR$ (Carbonyl between carbons)

Carboxylic acid

$COOH$ (Carbonyl + OH)

Ether

$COC$ (no carbonyl) - Oxygen bridge

Acid anhydride

$COOCO$ (Two carbonyls)

Sulfhydryl

$SH$ (Sulfur + H)

Disulfide

$S-S$ (Sulfur bridge)

Amino

$NH_2$ (Nitrogen + two H)

Quaternary amine

$N^*$ with 4 groups (Nitrogen with four carbon groups)

Ester

$COO$ (Carbonyl + O)

Thioester

$COS$ (Carbonyl + S)

Amide

$CONH$ (Carbonyl + N)

Phosphoester

$PO_4$ (Phosphate present)
