| 31. | The vibrational spectrum is indicative of the presence of a triple bond between the nitrogen and carbon atoms.
|
| 32. | This holds true with double and triple bonds, as you must break them multiple times to break their structure.
|
| 33. | Dicyanopolyynes are composed of a chain of carbon atoms with alternating single and triple bonds, terminated by nitrogen atoms.
|
| 34. | This also allows double and triple bonds to be approximated by multiple single bonds ( Fig . 3 ).
|
| 35. | For alkynes the most effective orientation is the external field in parallel with electrons circulation around the triple bond.
|
| 36. | This is done by mutually sharing three pairs of electrons between the two carbon atoms to form a triple bond.
|
| 37. | The single bond has the capacity for rotation, a property not possessed by the double bond or the triple bond.
|
| 38. | The Tersoff's model could describe single, double and triple bond energies in carbon structures such as in hydrocarbons and diamonds.
|
| 39. | A carbon carbon triple bond is also present in marketed drugs such as the antiretroviral Efavirenz and the antifungal Terbinafine.
|
| 40. | The carbon carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180?
