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

Which haloarenes is most reactive towards electrophilic substitution reaction ?

1.		2.
3.		4.

When chloroform is reacted with excess of NaOH then final product formed is 

1. HCOOH

2. ${\mathrm{CH}}_3\mathrm{COOH}$

3. ${\mathrm{CH}}_3\mathrm{COONa}$

4. HCOONa

The ease of aromatic nucleophilic substitution among these compounds will be in the order as :

1. IV > I > II >III

2. IV > III > II > I

3. III > II > IV >I

4. I > II > III > IV 

The hydrolysis reaction that takes place at the slowest rate among the following is

1.
2.	\(H_3CCH_2Cl~\xrightarrow{~~aq.~NaOH~~}H_3CCH_2OH~ \)
3.	\(H_2C=CHCH_2Cl~\xrightarrow{~~aq.~NaOH~~}H_2C=CHCH_2OH~ \)
4.

For the following : 
(i) I^- 
(ii) Cl^- 
(iii) Br^- 
The increasing order of nucleophilicity would be :

1. I^-<Br^-<Cl^-

2. Cl^-<Br^-<I^- 

3. I^- <Cl^-<Br^-

4. Br^-<Cl^-<I^-
