Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine , chlorine , and iodine , and tend to be intermediate between those of chlorine and iodine, the two neighbouring halogens.
Propargyl bromide, also known as 3-bromo-prop-1-yne, is an organic compound with the chemical formula HC≡CCH 2 Br. A colorless liquid, it is a halogenated organic compound consisting of propyne with a bromine substituent on the methyl group.

A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Bromine monochloride, also called bromine(I) chloride, bromochloride, and bromine chloride, is an interhalogen inorganic compound with chemical formula BrCl. It is a very reactive golden yellow gas with boiling point 5 °C and melting point −66 °C. Its CAS number is 13863-41-7, and its EINECS number is 237-601-4. [1]
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.

Bromine perchlorate can be produced from the reaction of cesium perchlorate and bromine fluorosulfate at -20 °C: [1] CsClO 4 + BrSO 3 F → BrOClO 3 + CsSO 3 F. Alternatively, it can also be produced by the reaction of chlorine perchlorate and bromine at -45 °C. Bromine perchlorate reacts with hydrogen bromide to regenerate bromine: [1 ...
