Question:
Identify the type of the reaction, represented below.
\(\text{C}_{2}\text{H}_{5}\text{-Br}+\text{OH}^{-}\rightarrow \text{C}_{2}\text{H}_{5}\text{-OH}+\text{Br}^{-}\)
Identify the type of the reaction, represented below.
\(\text{C}_{2}\text{H}_{5}\text{-Br}+\text{OH}^{-}\rightarrow \text{C}_{2}\text{H}_{5}\text{-OH}+\text{Br}^{-}\)
\(\text{C}_{2}\text{H}_{5}\text{-Br}+\text{OH}^{-}\rightarrow \text{C}_{2}\text{H}_{5}\text{-OH}+\text{Br}^{-}\)
Show Hint
Hydroxide is a nucleophile that replaces bromine on a saturated carbon.

- Nucleophilic substitution
- Electrophilic addition
- Electrophilic substitution
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Identify the attacking species and what happens to the substrate.
Step 2: Analyse the reaction
\(\text{OH}^{-}\) is a nucleophile that attacks the carbon bonded to bromine in \(\text{C}_{2}\text{H}_{5}\text{Br}\).
Step 3: Result
Bromide leaves and \(-\text{OH}\) takes its place. A group is substituted, not added, because the carbon is saturated.
Final Answer:
The reaction is a nucleophilic substitution. \[ \boxed{\text{(B) }\text{Nucleophilic substitution}} \]
