Answer:
In SnCl2,the tin is electrin deficient centre.Due to presence of two chlorine atoms the electron deficiencyagain increases. Hence erectron rich centre readily attacks to the electron deficient tin centre.Here sn centre acts as lewis acid. Hence chlorine centre acts as lewis basic
According to Lewis Theory of Acids and Bases, a Lewis Acid is an electron pair acceptor, while a Lewis Base is an electron pair donor. With this basic knowledge, let us analyze the structure of SiCl4. SiCl4 is a non-polar covalent compound which has tetrahedral geometry.
Lewis Acid or Base: AlCl3
It also doesn't complete an octet when the Lewis Structure is made and only has 6 electrons so it tries to accept any lone pair of electron to become stable.
