The geometry and dipole moment of $H_2S$ respectively are

Statement-$1$: $CCl_4$ and $H_2O$ are immiscible with each other. Statement-$2$: $CCl_4$ is a polar solvent.

Although both $CO_2$ and $H_2O$ are triatomic molecules,the shape of $H_2O$ molecule is bent while that of $CO_2$ is linear. Explain this on the basis of dipole moment.
