jarmenkill Posted May 29, 2010 Share Posted May 29, 2010 methane has 4 electrons groups so it has a 109 28' angel between CH bonds. for 3 groups of electrons we will have 120 degree(s) angel.(and so 3 bonds are in a plate) for example see BF3 for more info see VSEPR theory Link to comment Share on other sites More sharing options...
