Question

Ethyl magnesium iodide reacts with water to give?​

Answer 1

Answer:

You can use iodide in place of bromide here ok

Explanation:

The structure of ethyl magnesium bromide or Grignard reagent is –

Ethylmagnesium bromide is a Grignard reagent with formula C2H5MgBr

. It is widely used in the laboratory synthesis of many organic compounds.

Grignard reagents are made by adding halogenoalkane to magnesium in a flask having ethoxy – ethane (commonly known as diethyl ether or simply "ether"). The flask has a reflux condenser and the mixture is warmed over a water bath for nearly 20 - 30 minutes. Everything has to be perfectly dry because Grignard reagents react with water.

⇒CH3CH2Br+Mg−→−−−−−−ethoxyethaneCH3CH2MgBr

It is used as a strong base to remove protons from various substrates such as alkynes –

⇒RC≡CH+EtMgBr→RC≡CMgBr+EtH

Ethyl magnesium bromide is a good nucleophile, i.e., it is attracted to electron deficient chemical species.

Grignard reagents react with water to produce alkanes.

⇒CH3CH2MgBr+H2O→CH3CH3+Mg(OH)Br

The reaction of ethyl magnesium bromide with water will produce ethane. This is a wasteful process.

Answer 2

Ethyl magnesium iodide reacts with water to give ethane.
