Question:
Identify the product of reaction between alcoholic silver nitrite and ethyl bromide.
Identify the product of reaction between alcoholic silver nitrite and ethyl bromide.
Show Hint
AgNO2 is covalent, so attack is through nitrogen and gives a nitroalkane.
Updated On: Nov 12, 2026
- Ethene
- Ethane
- Ethane nitrile
- Nitro ethane
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Nitrite ion is an ambident nucleophile. Ionic nitrites (KNO2) give alkyl nitrites, while covalent AgNO2 gives nitroalkanes.
Step 2: Apply to the reaction
AgNO2 is covalent, so the lone pair on nitrogen attacks the carbon of ethyl bromide.
\(\text{C}_2\text{H}_5\text{Br}+\text{AgNO}_2\rightarrow\text{C}_2\text{H}_5\text{NO}_2+\text{AgBr}\)
Step 3: Compare the options
The product is nitroethane, the last option.
Final Answer:
The product is nitroethane. \[ \boxed{\text{(D) }\text{Nitro ethane}} \]
