Question

Use the localised electron model to describe the bonding in hydrogen cyanide and phosgene (COCl2)

Answer 1

Phosgene: Carbon is the central atom. It is connected via single bond to the Chlorine atoms and via a double bond to the oxygen atom. The oxygen atom has two lone pairs, while the chlorine atoms each have three lone pairs. The geometry of the molecule is sp² . And the geometry is trigonal planar

Hydrogen Cynaide: H-C\approxN is sp hybridized and has a Unear geometry. Nitrogen has a lone pair of electrons.
