Incorrect method of preparation for alcohols from the following is:
Incorrect method of preparation for alcohols from the following is:
Options
- AReaction of Ketone with followed by hydrolysis.
- BReaction of alkyl halide with aqueous .
- CHydroboration-oxidation of alkene.
- DOzonolysis of alkene
Correct answer
D. Ozonolysis of alkene
Step-by-step solution
Reacting a Grignard reagent with a ketone gives a tertiary alcohol. When alkyl halide reacts with aqueous sodium hydroxide to give alcohol, the reaction is called nucleophilic substitution. The Hydroboration Oxidation reaction is an organic chemical reaction which is employed for the conversion of alkenes into alcohols that are neutral. Reductive ozonolysis of alkenes will lead to formation of aldehyde or ketones, oxidative ozonolysis of alkenes will lead to formation of carboxylic acids or ketones.
So, alcohol is not formed by ozonolysis of alkenes.
