A compound composed of only carbon and chlorine is 85.5% chlorine by mass. Propose a Lewis structure for the lightest of the possible compounds that allows each atom to have a complete octet without formal charges.

Homework Answers

Answer #1

Ans :- The unknown compound is 1,1,2,2-Tetrachloroethene i.e. C2Cl4.

Explanation :-

Elements %age by mass Atomic mass Molar ratio Simple ratio Simplest whole number ratio
C 100- 85.5 = 14.5 g 12 g 14.5/12 =1.208 1.208/1.208 = 1 1
Cl 85.5 g 35.5 85.5/35.5 = 2.408 2.408/1.208 = 1.99 2

Since the simplest ratio of C :Cl = 1 : 2

Therefore

Empirical formula of the given species is CCl2 and lightest of the possible compounds that allows each atom to have a complete octet without formal charges is C2Cl4.

Lewis structure of C2Cl4 is :
