Which of the following steps is done first to determine the molecular shape of dichloromethane (CH₂Cl₂)? A) Calculate the molecular weight. B) Look up the bond angle of a H-C-H bond. C) Determine the electron geometry. D) Construct the Lewis structure. E) The molecular shape can be determined without doing any prior steps.

Question

Quizplus · Accepted Answer

To determine the molecular shape of dichloromethane, we need to first construct the Lewis structure. This will show us the arrangement of all atoms and the bonding electrons. From there, we can determine the electron geometry and then the molecular shape. Calculating the molecular weight and looking up bond angles are not necessary steps for determining molecular shape, and the molecular shape cannot be determined without first knowing the electron geometry.
