| 21. | The carbon atom has two additional single bonds.
|
| 22. | In chemistry, a "'single bond "'is a chemical bond between two atoms involving two valence electrons.
|
| 23. | The distinction is often important, because the double bond is chemically different from two single bonds.
|
| 24. | Last year, a Washington-based appeals court said all members of that institution must share a single bond.
|
| 25. | It also accounts for the free rotation around single bonds and for the tetrahedral geometry of methane.
|
| 26. | To preserve valence 4 for carbons, the opposite corners of the hexagon are connected by single bonds.
|
| 27. | The compound is protonated on another side, whereas a single bond and a double bond are exchanged.
|
| 28. | Both MM2 and ECEPP include potentials for H-bonds and torsion potentials for describing rotations around single bonds.
|
| 29. | Note that when used to refer to moieties, multiple single bonds differ from a single multiple bond.
|
| 30. | By behaving as two discrete alkenes joined by two single bonds, and therefore non-aromatic rather than antiaromatic.
