Question

Reactivity order of following towards $NaOE,\,EtOH$ :

• A. $3>2>1$
• B. $2>1>3$
• C. $1>2>3$
• D. $3>1>2$

Answer 1

Answer: (A)

$3>2>1$

Answer 2

Nucleophilic substitution of aryl halides is favoured by electron withdrawing substituent attached at ortho and para positions to the halide atom. So, reactivity order towards $NaOEt$ and $EtOH$ is:
