A three-membered ring containing a cation of this element is nucleophilically attacked by acetate to form a vicinal diol in the Woodward cis-hydroxylation.
A three-membered ring containing a cation of this element is nucleophilically attacked by acetate to form a vicinal diol in the Woodward cis-hydroxylation. An acid of this element and oxygen is used to cleave vicinal diols into carbonyls. This element binds to 7 fluorine atoms in a classical example of a pentagonal bipyramidal compound. This is the largest element that can bind to silver in a chemical used in (*) photographic film. Deficiency of this element in the human body leads to an enlarged thyroid, a condition known as goiter. This element is used to test for starch by staining it a blue-black color. The only diatomic element to be solid at room temperature, for 10 points, name this second-heaviest halogen, whose chemical symbol is I.
