Give the number of lone pairs around the central atom and the geometry of the ion IBr₂^-. A) 0 lone pairs, linear B) 1 lone pair, bent C) 2 lone pairs, bent D) 3 lone pairs, bent E) 3 lone pairs, linear

Question

Quizplus · Accepted Answer

The central atom, iodine, in IBr2^- has 7 valence electrons. With two bromine atoms forming bonds and an extra electron due to the negative charge, iodine has 10 electrons or 5 pairs. Two pairs are used for bonding, leaving 3 lone pairs. The geometry is linear due to the arrangement of electron pairs minimizing repulsion.
