31. It is a hydrocarbon and the simplest alkyne . 32. Terminal alkynes , including acetylene itself, can react with water to give aldehydes. 33. Alkynes react similarly, forming the tetrahalo compounds.34. In carbo-benzene the ring bonds are extended with alkyne and allene groups. 35. They also arise via carbonylation of alkynes and alkenes in the presence of thiols. 36. This compound reacts with 3-hexyne in an alkyne trimerization to the benzocarborane. 37. Palladium can also promote a radical addition of tin hydride to alkynes or alkenes. 38. Alkyne protons by contrast resonate at high field in a 2 3 ppm range.39. The diene is known to react with amines, aldehydes, alkenes and alkynes . 40. Also, what is the name for alkyne groups conjugated with a carbonyl system?
