The correct order of solvolyis in the following alkyl halide is 

Arrange the following halides in the decreasing order of S_N1 reactivity:

(I) ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{Cl}$

(II) ${\mathrm{CH}}_2=\mathrm{CHCH}\left(\mathrm{Cl}\right){\mathrm{CH}}_3$

(III) ${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{CH}\left(\mathrm{Cl}\right){\mathrm{CH}}_3$

1. I > II > III

2. II > I > III

3. II > III > I

4. III > II > I

Replacement of 'Cl' of  chlorobenzene to give phenol requires drastic conditions but chlorine of 2,4- dinitrochloro benzene is readily replaced because

1. ${\mathrm{NO}}_2$ makes the ring electrons rich at ortho and para position

2. ${\mathrm{NO}}_2$ withdraws electrons from meta position

3. ${\mathrm{NO}}_2$ donates electrons at m-position

4. ${\mathrm{NO}}_2$ withdraws electrons from ortho and para positions 

Among the following bromides given below, the order of their reactivity in the S_N1 reaction is 

1. III > II > I

2. II > III > I

3. III > I > II

4. II > I > III
