Using Lewis structures, discuss the reasons for the difference in bond angles of these two molecules. Alkanes are in some respect the most boring of the organic compounds, since they are unreactive (mostly) towards acids, bases, oxidizing agents, reducing agents, and most of the other reagents that organic chemists have in their arsenals. Having a MSc degree helps me explain these concepts better. It also depends on the electronegativity of the molecules participating in the formation of the compound. The compound has twenty valence electrons, out of which eight electrons participate in bond formation. Circle your answer. Set your categories menu in Theme Settings -> Header -> Menu -> Mobile menu (categories). Still have questions? It is well established that the normal carbon atom forms its four single bonds in compounds of the type $$CX_4$$ so that the four attached atoms lie at the corners of a regular tetrahedron.
