Reaction with Anhydrous HI:
The reaction of CH3-O-C2H5 (also known as ethyl methyl ether) with anhydrous hydrogen iodide (HI) results in the formation of ethanol and methyl iodide. This reaction is an example of nucleophilic substitution.

Mechanism:
1. Protonation: The first step involves the protonation of the ether oxygen atom by the strong acid, HI. The oxygen atom of the ether acts as a nucleophile and attacks the hydrogen ion, forming an oxonium ion.

2. Nucleophilic Substitution: In the next step, the nucleophilic oxygen atom attacks the carbon atom of the methyl group in the oxonium ion. This leads to the formation of a new carbon-oxygen bond and the breaking of the carbon-iodine bond.

3. Elimination: Finally, the iodide ion is protonated by another molecule of HI, resulting in the formation of methyl iodide, which is a volatile compound, and ethanol.

Overall Reaction:
CH3-O-C2H5 + HI → CH3-I + C2H5OH

Reaction with Concentrated HI:
The reaction of CH3-O-C2H5 with concentrated HI involves the cleavage of the carbon-oxygen bond, leading to the formation of ethyl iodide and methanol. This reaction is an example of hydrolysis.

Mechanism:
1. Protonation: Similar to the previous reaction, the first step involves the protonation of the ether oxygen atom by the acid. The oxygen atom of the ether acts as a nucleophile and attacks the hydrogen ion, forming an oxonium ion.

2. Cleavage: In the next step, the oxonium ion undergoes cleavage of the carbon-oxygen bond. This results in the formation of a carbocation and an alcohol molecule.

3. Nucleophilic Substitution: The carbocation intermediate is then attacked by the iodide ion, which acts as a nucleophile. This leads to the formation of ethyl iodide and regenerates the acid catalyst.

Overall Reaction:
CH3-O-C2H5 + HI → C2H5I + CH3OH

Summary:
In summary, when CH3-O-C2H5 reacts with anhydrous HI, ethanol and methyl iodide are formed through a nucleophilic substitution reaction. On the other hand, when it reacts with concentrated HI, ethyl iodide and methanol are formed through a hydrolysis reaction.

Similar NEET Doubts

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
