How many electron groups are around beh2
WebNote: the electron pair distribution and the molecular geometry are different if there are lone pairs of electrons present. Having determined the arrangement of electron pairs, take off one “arm” of the structure for every lone pair present. Multiple bonds are treated as a single area of electrons; ie the carbon of CO 2 contains two areas of WebGroup is used when a central atom has two terminal atoms bonded by single bonds and a terminal atom bonded with two pairs of electrons (a double bond). In this case there are three groups of electrons around the central atom and the molecualr geometry of the molecule is defined accordingly.
