Phosgene, a substance used in poisonous gas warfare during World War I, is so named because it was first prepared by theaction of sunlight on a mixture of carbon monoxide and chlorine gases. Its name comes from the Greek words phos (light) andgenes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, and 71.69% Cl by mass. Its molarmass is 98.9 g>mol. (a) Determine the molecular formula of this compound. (b) Draw three Lewis structures for the moleculethat satisfy the octet rule for each atom. (The Cl and O atoms bond to C.) (c) Using formal charges, determine which Lewisstructure is the dominant one. (d) Using average bond enthalpies, estimate ΔH for the formation of gaseous phosgene fromCO(g) and Cl21g2.

Question

Phosgene, a substance used in poisonous gas warfare during World War I, is so named because it was first prepared by the
action of sunlight on a mixture of carbon monoxide and chlorine gases. Its name comes from the Greek words phos (light) and
genes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, and 71.69% Cl by mass. Its molar
mass is 98.9 g>mol. (a) Determine the molecular formula of this compound. (b) Draw three Lewis structures for the molecule
that satisfy the octet rule for each atom. (The Cl and O atoms bond to C.) (c) Using formal charges, determine which Lewis
structure is the dominant one. (d) Using average bond enthalpies, estimate ΔH for the formation of gaseous phosgene from
CO(g) and Cl21g2.
