hydroxyl

Definitions

Examples

• This pair is called a hydroxyl group and has a tiny negative charge.

• Specifically, small compounds called hydroxyl groups, which consist of hydrogen and oxygen atoms, do most of the work.

• The assumption was that it was in the form of hydroxyl, which is made of one oxygen atom and one hydrogen atom—a stable molecule that would naturally form in a regolith where oxygen is also present.

• Another toxic component of the fuel was hydroxyl-terminated polybutadiene, a form of rubber.

• Those four atoms are called the methyl group, and a methyl group combined with a hydroxyl group forms methyl alcohol.

• First, the hydrogen is displaced by the chlorine: then the chlorine is turned out and its place taken by the hydroxyl.

• It is best detected in acid solutions by the deep brown or iodine colour developed on adding hydroxyl.

• Now these phenols are all more or less acid in character by virtue of the hydroxyl-group which they contain.

• The substitution of a hydrogen atom by the hydroxyl group generally occasions a rise in boiling-point at about 100.
