There are two lone pair of electrons present on oxygen atom which are not taking part in and formation. In molecule of Methanol as shown below, it can be seen that carbon atom is forming four bonds with three hydrogen atoms and one oxygen atom by sharing four electron pairs and oxygen is forming two bonds, one with carbon atom and one with hydrogen atom. A 85.2-mg sample of the compound X4O10 contains 48.0 mg of oxygen atoms. 1. The number of electrons are 6 that means the hybridization will be and the electronic geometry of the molecule will be octahedral. Explain why materials with metallic lattice structures can be used to make wires and connections that conduct electricity in electrical circuits. Since in CH3OH, different atoms are bonded together, all of the bonds are polar. Draw a diagram: Draw a Lewis diagram of the oxygen molecule in the space below at left.
