Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A molecule of $S i C l_{4}$ is non polar as all the $S i - C l$ bond being identical cancels each other $μ$ . Hence net $μ = 0$ . Thus $S i C l_{4}$ is non polar.

Assertion :A molecule of silicon SiCl5, is nonpolar. Reason: The four bonds in SiCl4 are identical and the molecule has a tetrahedral structure.

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for AssertionA molecule of SiCl4 is non polar as all the Si−Cl bond being identical cancels each other μ. Hence net μ=0. Thus SiCl4 is non polar.
