The approximate bond angle is about 104.5 degree.įor BCl3, the boron atom is surrounded by three electron pairs and the three electron pairs are all bonding pairs. Hence the bond angle is even smaller than 107. The repulsive force between lone pair - lone pair is greater than between the lone pair - bond pair. The approximate bond angle is about 107 degree.įor SF2, the sulphur atom is surrounded by four electron pairs but there are two bonding pairs and two lone pairs. Hence the bond angle is slightly smaller than 109.5. The repulsive force between lone pair - bond pair is greater than the bond pair - bond pair. Therefore, the shape of NI3 is trigonal pyramidal. Therefore they have the tetrahedral shapes with the approximate bond angles of 109.5 degree.įor NI3, the nitrogen atom is surrounded by four electron pairs but there are three bonding pairs and one lone pair.
The carbon atom is surrounded by four electron pairs and all the electron pairs are the bonding pairs. CCl4, CF4 and CCl2F2 come under the same category.
