Alcohols

Question 1

What are the methods of preparation of alcohols

Answer 1

*hydration of alkenes
*hydrolysis of alkyl halide
*reaction of aldehyde/ketones with grignard reagent (CH3-MG-X)

Question 2

explain the reaction of hydration of alkenes

Answer 2

1: react alkene with a reagent (H2SO4)
2: because of markonikov’s rule, the H will react with CH2 alkene, and will from
CH3-CH-CH3
I
OSO3H
3: the product will react with H2O and form, CH3-CH-CH3 + H2S04
I
OH

Question 3

reaction of hydrolysis of alkyl halide

Answer 3

alkyl halide reacts with alkali (KOH)
K reacts with halogen
OH takes place of halogen

Question 4

write the reaction of hydrolysis of alkyl halide on your textbook

Answer 4

:)

Question 5

explain the reaction of grignard reagent with aldehyde

Answer 5

reaction of grignard reagent with formaldehyde
