What is the action of the following on ethyl bromide ?
(a) silver nitrite
(b) Mg in dry ether
(c) alcoholic sodium hydroxide
Question: 1
Silver Nitrite
Silver Nitrite
Show Hint
Silver nitrite favors the formation of alkyl nitrites \( (R-ONO) \), whereas alkali metal nitrites \( (\text{NaNO}_2) \) form alkyl nitro compounds \( (R-NO_2) \).

Hide Solution
Verified By Collegedunia
Solution and Explanation
When ethyl bromide reacts with silver nitrite (\(\text{AgNO}_2\)), ethyl nitrite is formed due to the ambident nature of the nitrite ion.
\[
\text{C}_2\text{H}_5\text{Br} + \text{AgNO}_2 \rightarrow \text{C}_2\text{H}_5\text{ONO} + \text{AgBr}
\]

Question: 2
Magnesium in Dry Ether
Magnesium in Dry Ether
Show Hint
Grignard reagents \( (R-MgBr) \) are highly reactive and can be used for nucleophilic addition reactions with carbonyl compounds.

Verified By Collegedunia
Solution and Explanation
Ethyl bromide reacts with magnesium in dry ether to form an ethyl magnesium bromide (Grignard reagent).
\[
\text{C}_2\text{H}_5\text{Br} + \text{Mg} \xrightarrow{\text{dry ether}} \text{C}_2\text{H}_5\text{MgBr}
\]

Question: 3
Alcoholic Sodium Hydroxide
Alcoholic Sodium Hydroxide
Show Hint
Alcoholic NaOH promotes elimination (E2) reactions, forming alkenes, whereas aqueous NaOH promotes nucleophilic substitution (SN2).
Updated On: Mar 4, 2025
Hide Solution
Verified By Collegedunia
Solution and Explanation
Ethyl bromide undergoes dehydrohalogenation in the presence of alcoholic sodium hydroxide (\(\text{NaOH}\)), leading to the formation of ethene.
\[
\text{C}_2\text{H}_5\text{Br} + \text{alc. NaOH} \rightarrow \text{C}_2\text{H}_4 + \text{HBr}
\]
