Question

A Bromine shows its highest positive oxidation state, in an interhalogen
when it combines with
(i) chlorine
(ii) iodine
(iii) fluorine​

Answer 1

Answer:

IODINE

Explanation:

Answer 2

There are six elements in Group VIIA, the next-to-last column of the periodic table. As expected, these elements have certain properties in common. They all form diatomic molecules (H2, F2, Cl2, Br2, I2, and At2), for example, and they all form negatively charged ions (H-, F-, Cl-, Br-, I-, and At-).

When the chemistry of these elements is discussed, hydrogen is separated from the others and astatine is ignored because it is radioactive. (The most stable isotopes of astatine have half-lives of less than a minute. As a result, the largest samples of astatine compounds studied to date have been less than 50 ng.) Discussions of the chemistry of the elements in Group VIIA therefore focus on four elements: fluorine, chlorine, bromine, and iodine. These elements are called the halogens (from the Greek hals, "salt," and gennan, "to form or generate") because they are literally the salt formers.

THEREFORE ANSWER IS IODINE

None of the halogens can be found in nature in their elemental form. They are invariably found as salts of the halide ions (F-, Cl-, Br-, and I-). Fluoride ions are found in minerals such as fluorite (CaF2) and cryolite (Na3AlF6). Chloride ions are found in rock salt (NaCl), the oceans, which are roughly 2% Cl- ion by weight, and in lakes that have a high salt content, such as the Great Salt Lake in Utah, which is 9% Cl- ion by weight. Both bromide and iodide ions are found at low concentrations in the oceans, as well as in brine wells in Louisiana, California, and Michigan.
