Question

Silicones are polymeric compounds containing, among others, the following types of covalent bonds: Si–O, Si–C, C–H, and C–C. Using the electronegativity values as shown, arrange the bonds in order of increasing polarity and designate the positive and negative atoms using the symbols δ+ and δ–.
