Possible answer:

Products of Ethyl Bromide Treatment with Moist Ag2O

When ethyl bromide (C2H5Br) is treated with moist silver oxide (Ag2O), the following reactions can occur:

C2H5Br + Ag2O + H2O → C2H5OH + 2 AgBr + H2O
C2H5Br + Ag2O + 2 H2O → C2H5-O-C2H5 + 2 AgOH + 2 HBr

The first equation shows the formation of ethanol (C2H5OH) and silver bromide (AgBr) as the main products. The second equation shows the formation of diethyl ether (C2H5-O-C2H5) and silver hydroxide (AgOH) as the main products. Therefore, the correct answer is (d) all of the above, as both ethanol and ether can be formed depending on the conditions and the amount of Ag2O used.

Explanation of the Reactions

The treatment of ethyl bromide with moist Ag2O involves the nucleophilic substitution of the bromine atom (Br) by the hydroxide ion (OH-) from water (H2O) or silver hydroxide (AgOH) in the presence of excess water. This process leads to the formation of a silver halide (AgX) and an alcohol (ROH), where R is the alkyl group. The mechanism can be described as follows:

C2H5Br + AgOH → C2H5-OH + AgBr

However, if the reaction is carried out with insufficient water or AgOH, or if the temperature is too high, the alcohol can undergo dehydration to form an ether. This process involves the elimination of a water molecule from two alcohol molecules, which requires a strong acid catalyst such as sulfuric acid (H2SO4). The mechanism can be described as follows:

2 C2H5-OH → C2H5-O-C2H5 + H2O

Therefore, the formation of ether is favored when the concentration of water is low and the temperature is high, while the formation of alcohol is favored when the concentration of water is high and the temperature is low.

Conclusion

In summary, the treatment of ethyl bromide with moist Ag2O can lead to the formation of both ethanol and diethyl ether, depending on the conditions and the amount of Ag2O used. The reactions involve nucleophilic substitution and dehydration mechanisms and can be influenced by the concentration of water, the concentration of AgOH, the temperature, and the presence of acid catalysts.

It can form di ethly ether or may be even ethanol depending on the concentration of moist silver oxide.
