Which of the following option is/are correct regarding ${\mathrm{SO}}_2{\mathrm{Cl}}_2$?  

$\mathrm{OSO}>\mathrm{OSCl}>\mathrm{Cl}\hat{\mathrm{S}}\mathrm{Cl}$  (bond angle)

It has two $\mathrm{p\pi }-\mathrm{d\pi }$ bonds

Number of  $\mathrm{p\pi }-\mathrm{d\pi }$ bonds is equal to number of $\mathrm{p\pi }-\mathrm{d\pi }$ bonds

Hybridisation of S is $s{p}^3$
