(DAILY DOUBLE). When drawing a lewis dot diagram for CHCl3, Will included 3 chlorine atoms and one hydrogen atom, each with 6 valence electrons. At the centre, he had one carbon with 4 bonds. His total number of valence electrons were 32. What did he do wrong and how many valence electrons should he have
You cannot have 6 electrons on the terminal hydrogen which only wants 2. The correct number of valence electrons is 26.
