Alcohol Molecules |
||||||
 |
||||||
|
||||||
| Alcohol molecules can possess one, two, or three hydroxyl (OH-) groups. Molecules containing one hydroxyl group are monohydric ("mono-" meaning "one"), those with two hydroxyl groups are dihydric ("di-" indicating "two"), and those with three are trihydric ("tri-" meaning "three"). The number of hydroxyl groups affects the properties of the compound. Methanol is a light, volatile liquid while ethylene glycol (recommended name ethane-1,2-diol) is viscous, and glycerol (or glycerine, or the recommended scientific name propane-1,2,3-triol) is the most viscous of the three. | ||||||
