Question

The correct structure of tribromo octaoxide is :
a.)

b.)

c.)

d.)

Answer 1

Hint:. The tribromo octaoxide is a neutral molecule and does not contain any charge. The structure of molecules contain all oxygen atoms bonded with double bonds with bromine atoms. The molecule contains three bromine atoms and eight oxygen atoms.

Complete step by step answer:
Bromine combines with oxygen to give a variety of oxides. The tribromo octaoxide is the oxide of bromine that contain three bromine atoms and eight oxygen atoms. The structure of the oxide is as-

The two terminal bromine atoms bond with three oxygen atoms and a Br-Br bond. The central bromine atom forms a double bond with two oxygen atoms and a single bond with two bromine atoms. The molecule is neutral overall and does not contain any charge.
So, the correct answer is “Option A”.

Additional Information:
Bromine is a red brown liquid that evaporates very easily as the cap of the bottle is opened. It is corrosive and its vapours can irritate eyes and throat. The bromine higher oxides are least stable if we compare them with other halide oxides because these lack high polarity and multiple bond formation that involve the use of d orbitals. The chlorine oxides form multiple bonds with the help of d- orbitals.

Note: Bromine can form a variety of oxides. Some are dibromine monoxide, bromine dioxide, dibromine trioxide and dibromine pentoxide etc. Even a number of ions are bromine oxides like hypobromite, bromite, bromate and perbromate etc.
