Question

The decreasing order of reactivity of the following organic molecules towards AgNO₃ solution is ______.

1. 
   
2. 
   
3. \[\begin{array}{cc}\ce{CH3CHCH3}\\
   |\phantom{..}\\\ce{Cl}\phantom{.}\end{array}\]
4. \[\begin{array}{cc}\ce{CH3CHCH2NO2}\\
   |\phantom{......}\\\ce{Cl}\phantom{.....}\end{array}\]

Options

• (C) > (D) > (A) > (B)

• (A) > (B) > (D) > (C)

• (A) > (B) > (C) > (D)

• (B) > (A) > (C) > (D)

Answer 1

The decreasing order of reactivity of the following organic molecules towards AgNO₃ solution is (B) > (A) > (C) > (D).

Explanation:

(A) 

(B)

(C) \[\begin{array}{cc}
\ce{CH3CHCH3 ->[- Cl-] CH3 - \overset{⊕}{C}H - CH3}\\
|\phantom{....................}\ce{(2^\circ)}\phantom{..}\\
\ce{Cl}\phantom{...................}\ce{(iii)}\phantom{...}
\end{array}\]

(D) \[\begin{array}{cc}
\ce{CH3 - CH - CH2 - NO2 ->[- Cl-] CH3 - \overset{⊕}{C}H - CH2 - NO2}\\
\phantom{........}|\phantom{.............................}\ce{(iv)}\phantom{.........}\ce{(- I)}\\
\ce{Cl}\phantom{......................................}
\end{array}\]

Stability of C⁺: ii > i > iii > iv

Reactivity order: B > A > C > D
