N-Bromosuccinimide provides Br+ as an electrophile, which is followed by Br from LiBr.[2]. 3. This step can be avoided for neutral compounds. CH2Br2 Molecular Geometry - Science Education and Tutorials According to the VSEPR theory, if the CH2Br2 molecule has an AX4 generic formula, the molecular geometry and electron geometry will both be tetrahedral forms. -> central atom is C . 4. Before drawing the Lewis structure, we need to know the number of valence shell electrons on all constituent atoms and their sum. Lewis Structures. He holds a degree in B.Tech (Chemical Engineering) and has four years of experience as a chemistry tutor. However, the repulsions of the bonding electron pairs on the CH3 molecule are no longer balanced by the fourth pair (from the CC bond), so the molecule flattens out to form a trigonal planar geometry.
