What reagent is needed to convert 1-hexyne to 2-hexanone?
(a) o3 /zn/ h3o
(b) pcc (pyridinium chlorochromate)
(c) bh3 /h2o2 /oh-
(d) h2o/h

Sagot :

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.
