which of the following easily gives white ppt of AgCl with silver nitrate?

Question:-

Which of the following easily gives white ppt of  AgCl  with silver nitrate?

 

Option:-

a.  CH₃—Cl 

b.  CH₃—CH₂—Cl

c.  (CH₃)₂C—Cl

d.  (CH₃)₃C—Cl

 

Answer:-  (d)

 

Explanation:-

Their Carbocation and stability order:-

a.      CH₃⁺       <    b.  CH₃—C⁺H₂   <    c.  (CH₃)₂C⁺   <    d.  (CH₃)₃C⁺

a.      Methyl carbocation  <  b. 1’C  <  c. 2’ C  <  d. 3’C

So reactivity order:-

a.      CH₃—Cl    <   b.  CH₃—CH₂—Cl   <   c.  (CH₃)₂C—Cl   <   d.  (CH₃)₃C—Cl
