Respuesta :
The reagent is needed to convert 1-hexyne to 2-hexanone is [tex]H_{2}O /H^{+}[/tex].
So , option D is correct one.
Ozonolysis is used to form aldehyde and ketone from alkene not alkyne .So option A is incorrect .
The reagent PCC is used as an oxidant and is used to convert primary and secondary alcohol into aldehyde and ketone.
The [tex]BH_{3} /H_{2} O_{2} /OH^{-}[/tex] is used to convert alkene into alcohol which is known as hydroboration reaction.
The addition of a hydroxyl group to an alkyne causes tautomerization which subsequently forms a carbonyl Markovnikov addition of a hydroxyl group to an alkyne forms a ketone. So, [tex]H_{2}O /H^{+}[/tex] is used to convert alkyne into ketone.This reagent is needed to convert 1-hexyne to 2-hexanone.
