Let us now start knowing more about the compound from a different perspective like its 2D and 3D representation, polarity, and more. Due to the presence of two lone pairs of electrons that repel bond pairs N-H, it acquires a bent V-shape molecular shape with a bond angle of 104.5. The difference between C and H values is not quite significant but when it comes to the 2 C-O bonds, we will have a partial + on C and a - on O atom. This atom has four atoms directly attached and no lone pairs. According to this theory, the electron pairs that surround an atom in the center repel each other, which determines the form of the molecule. The central C atom has three electron groups around it because the double bond counts as one electron group. We know that the C-O bond is polar due to the difference between the electronegativities of carbon and oxygen. The nature of the polarity of CH3CH2OH is also a factor in its chemical reaction reactivity. Again there are four atoms forming bonds with the Carbon atom, and thus it requires four hybrid orbitals.
