Statement(I) : $C{O}_2$ has no dipolemoment where as $S{O}_2$ and $H_{2}O$ have dipolemoment.

Statement(II) : $SnC{l}_2$ is ionic, where as $SnC{l}_4$ is covalent which of the following is correct 

(a) ${\mathrm{CO}}_2$ has linear structure while ${\mathrm{SO}}_2$and ${\mathrm{H}}_2\mathrm{O}$ have V-shaped structures. Hence, dipole moment in ${\mathrm{CO}}_2$ is cancelled out but ${\mathrm{SO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ posses a dipole moment.

(b) Low charge on the cation favors the formation of Ionic bond. Hence SnCl₂(Sn⁺²) is Ionic and SnCl₄(Sn⁺⁴) is covalent.
