Question

part (b). In these compounds the atoms are bonded to one central atom: CIFO S (a) Following the approach of Lecture 11, correctly calculate the number of electrons around the central atoms. 2. CLI ClOSej (Note: you will lose all points if use a different approach). ) Predict the best arrangements of the e pairs to minimize repulsions to any lone-pairs and/or multiple bonds, then sketch a clear correct structure for each compound. Show unambiguously bonds in and out of the plane of vour drawing (follow examples of Lectures 11 and 12). Show lone pairs on the central atom (when present); do not show any other electrons (Note: you will lose ½ point for every electron pair that isn't a lone pair on the central atom). (c) Name the arrangements of the electron pairs around the central atom and the molecular structures (shapes) in part (b).
