(1) 

(2)
(3)        

(4) Both (1) and (2)

$\mathrm{Cl}-{\mathrm{CH}}_2-\underset{{\mathrm{CH}}_3}{\overset{{\mathrm{CH}}_3}{\underset{\left|}{\overset{\right|}{\mathrm{C}}}}}-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{Cl}+{\mathrm{I}}^{-}<mspace\; width="1em"></mspace><mspace\; width="1em"></mspace><mspace\; width="1em"></mspace><mspace\; width="1em"></mspace>---><mspace\; width="1em"></mspace>\mathrm{Product}$
The major product of the above reaction is:-

1.$\mathrm{I}-{\mathrm{CH}}_2-\underset{{\mathrm{CH}}_3}{\overset{{\mathrm{CH}}_3}{\underset{\left|}{\overset{\right|}{\mathrm{C}}}}}-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{Cl}$

2. $\mathrm{Cl}-{\mathrm{CH}}_2-\underset{{\mathrm{CH}}_3}{\overset{{\mathrm{CH}}_3}{\underset{\left|}{\overset{\right|}{\mathrm{C}}}}}-{\mathrm{CH}}_2-{\mathrm{CH}}_2-\mathrm{I}$

3. ${\mathrm{H}}_2\mathrm{C}=\stackrel{{\mathrm{CH}}_3}{\stackrel{|}{\mathrm{C}}}-{\mathrm{CH}}_2-{\mathrm{CH}}_2=\mathrm{Cl}$

4. $\mathrm{Cl}-{\mathrm{CH}}_2-\underset{{\mathrm{CH}}_3}{\overset{{\mathrm{CH}}_3}{\underset{\left|}{\overset{\right|}{\mathrm{C}}}}}-{\mathrm{CH}}_2={\mathrm{CH}}_2$
