The Lewis structure of the molecule CHCl3 chloroform can be drawn as follows: Cl |H - C - Cl | ClTo determine the total number of valence electrons in CHCl3, we need to consider the valence electrons of each atom:- Carbon C has 4 valence electrons.- Hydrogen H has 1 valence electron.- Chlorine Cl has 7 valence electrons, and there are 3 chlorine atoms in the molecule.So, the total number of valence electrons in CHCl3 is:4 C + 1 H + 3 * 7 Cl = 4 + 1 + 21 = 26 valence electrons.
