The C-H bond is considered non-polar due to the difference in electronegativy if the atoms. an ion and a polar molecule; the strength is proportionate to the size of polar molecule. The covalent bonds can be polar or nonpolar depending upon various factors. Electronegative atoms can also give polarity to a molecule. Short-chain alcohols like methanol, propanol, and ethanol are miscible in water. Res. The Lewis dot structure provides a simple model between the bonds in a molecule and the lone electron pairs. They share all electron pairs.
