Structure of BrF3 Molecule  The central atom Br has seven electrons in the valence shell. Three of these will form electron-pair bonds with three fluorine atoms leaving behind four electrons. Thus, there are three bond pairs and two lone pairs. According to VSEPR theory, these will occupy the corners of a trigonal bipyramid. The two lone pairs will occupy the equatorial positions to minimise lone pair -lone pair and the bond pair -lone pair repulsions which are greater than the bond pair-bond pair repulsions. In addition, the axial fluorine atoms will be bent towards the equatorial fluorine in order to minimise the lone-pair lone-pair repulsions. The shape would be that of a slightly bent T.

Nomenclature      It is estimated that the number of species known and described ranges between 1.7 to 1.8 million. They are called by their local names (in regional languages),which vary from place to place and even within the same country. So there is need to standardise the naming pattern of living organisms such that a particular organism is known by the same name all over the world/universally. This process of naming of animals with a per the guide lines of the International code of zoological nomenclature (ICZN).   Binomial nomenclature (originally called binomial nomenclature) is used in naming organisms all over the world. 1.
