Respuesta :
IBr3 has three single bonds between the Iodine (I) and Bromine (Br) atoms in its Lewis structure. The Iodine atom (I) is in the centre, surrounded by three Bromine atoms (Br).
The Iodine atom has two lone pairs, while all three Bromine atoms have three. Because the overall formal charge is zero, the Lewis structure of PBr 3 described above is the most appropriate, reliable, and stable in nature. In PBr 3, there are three bonding pairs of electrons and one lone pair of electrons. The molecule will shape itself in such a way that repulsive forces are minimised.
The number of lone pairs of electrons present around the central atom is also denoted by the Lewis Structure. Ionic, covalent, and coordination compounds can all have Lewis structures. However, we can only draw it if we know the compound's molecular formula.
