(b)
Interpretation:
Reagents should be predicted for the given transformations.
Concept introduction:
Reagent: reagent is a compound or compound mixture that is used in the chemical transformation of the reactions. Reagents for some reactions are given below.
Hydroboration-oxidation: Generally alkenes react with boron followed by hydrogen peroxide and in presence of base like sodium hydroxide it gives corresponding alcohol and it follows anti-Markovnikoff rule.
Anti-Markovnikoff Rule: Alkenes belong to the group of unsaturated hydrocarbons that is one molecule of alkene contains at least one double bond. Due to the presence of pi electrons, they show addition reactions attacks carbon-carbon double bond to form the additional products.
To find: The reagent for the given transformation.
