41. The product contains a new exocyclic double bond . 42. The molecule carries a double bond which induces significant ring strain and significant reactivity. 43. Cyanamide adds itself in the presence of N-bromosuccinimide to olefinic double bonds . 44. Aromatic amino acids are able to absorb light due to their conjugated double bonds . 45. The color intensifies with increasing number of double bonds in the molecule being stained. 46. These free electron then attack the double bonds of resin monomers resulting in polymerization. 47.
