31. To conduct electricity, however, a polymer's pattern must feature alternating double and single bonds between its carbon atoms. 32. An amine always has three single bonds , whereas an isocyanide has only one single and one multiple bond. 33. The instability of this compound is mainly due to the hydroxylammonium ion's weak nitrogen to oxygen single bond . 34. The smallest theoretical C C single bond obtained in this study is 131 pm for a hypothetical tetrahedrane derivative. 35. Other related class of compounds have three or more double bonds, but they are not alternating with single bonds . 36. Saturated cyclic compounds contain single bonds only, whereas aromatic rings have an alternating ( or conjugated ) double bond. 37. This also allows double and triple bonds to be approximated by multiple single bonds ( Fig . 3 ). 38. Market participants have been in favour of the product being cash settled and being available on a single bond . 39. It interacts with a single bond in the targeted ribosome and breaks it, causing the ribosome to be inactivated. 40. The single bonds are formed from overlap of hybridized atomic p-orbitals above and below the plane of the ring.
