Correspondingly, what is the difference between electron groups and bonding groups?
The repulsive forces between bonding and non-bonding electrons determine the three-dimensional geometry of the “groups” of electrons around a central atom. A “group” of electrons can be a single bond, double bond, triple bond, or a lone pair of electrons.
Also, is ch2o trigonal planar? There are no lone pairs, so this is also the molecular geometry. (b) CH2O There are 4 valence electrons in carbon, 1 each in hydrogen and 6 in oxygen, so there are 12 electrons total. The e.d. geometry is trigonal planar, and because there are no lone pairs, the molecular geometry is also trigonal planar.
Herein, what is the electron group arrangement of ch4?
For example; four electron pairs are distributed in a tetrahedral shape. If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3).
How many electron groups are there?
The four electron groups are the 2 single bonds to Hydrogen and the 2 lone pairs of Oxygen. Since water has two lone pairs it's molecular shape is bent. According to the VSEPR theory, the electrons want to minimize repulsion, so as a result, the lone pairs are adjacent from each other.
