List of polymers with their uses is helpful in … This happens when there is a difference between the electronegativity values of each atom. In other words, we take long chain molecules and break it down into pieces. In general, if the electronegativity difference between two atoms is less than 0.5, the bond is considered nonpolar, even though the only truly nonpolar molecules are those formed with identical atoms. Adrenaline is a hormone synthesized in the adrenal medulla.
