Answer 1

Answer:

Acetylide,Enol, Aldehyde, Tautomers,Alkynes,Hydroboration,Keto.

Explanation:

Acetylide anions are strong nucleophiles that open epoxide rings by an SN2 mechanism.

Enol tautomers have an O-H group bonded to a C=C.

Aldehyde are formed from terminal alkynes with the addition of water using BH3 then H2O2.

Tautomers are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other.

Alkynes are compounds that contain a carbon-carbon triple bond.

Hydroboration of a terminal alkyne adds BH₂ to the less substituted, terminal carbon.

Keto tautomers have a C=O and an additional C-H bond.
