Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP). From the BP and LP interactions we can predict both the relative positions of the atoms and the angles between the bonds, called the bond angles. From this we can describe the molecular geometry. The VSEPR model can be used to predict the ...

- 3.2.2: Multiple Bonds
Double and triple bonds distort bond angles in a way similar to what lone pairs do. Due to the stronger repulsion, double and triple bonds occupy positions similar to those of lone pairs in groups with 5 and 6 electron groups.
The bond angle is the angle between any two adjacent bonds and is usually measured in degrees [1-4]. Bond Angles and VSEPR Theory. The valence shell electron pair repulsion (VSEPR) theory is used to study bond angles. This theory predicts a molecule’s shape based on the number of bonding and lone pairs.
According to VSEPR theory, the three regions of electron density (two C-H single bonds and one C-C double bond) around each carbon atom repel each other, arranging in a trigonal planar geometry. This leads to a bond angle of approximately 120° around each carbon atom.

A bond angle is the angle between any two bonds that include a common atom, usually measured in degrees. A bond length (or bond distance) is the distance between the nuclei of two bonded atoms along the straight line joining the nuclei. Bond lengths are measured in Ångstroms (1 Å = 10 –10 m) or picometers (1 pm = 10 –12 m, 100 pm = 1 Å).
