In ether the R groups connected to Oxygen can be both Alkyl, or Both Acyl, or even one of each for ethereal oxygen linkage. Multiple bonds (double and triple), however, contains sigma and pi bonds. In the diagram each line represents one pair of shared electrons. Dipole Moment is a term used to describe the measure of polarity between two charges at a distance by the equation (M=QR) The polarity of two atoms causes dipole interactions to be formed. The C-C atoms are triple bonded and to each C atoms are bonded one H atom with a single bond. When a base is used, saponification takes place, this is where the positive ion forms a salt with what used to be the acid of the ester and an alcohol will be formed with a negative ion. Chloroform is polar because the C-H bond is not polar so the C-Cl bonds create a dipole moment due to polarity. Join Yahoo Answers and get 100 points today.
