The bonds in the SiCl₄ molecules more polar.The polarity of bonds within a molecule depends on the difference of electronegativity of the atoms involved in the link. The chlorine is more electronegative atom than iodine. Therefore, the electrons in the Si-Cl bond will be more concentrated near the Cl, the creation of polarity in the bond. The iodine is not as electronegative, so it will not result in a very polarized si-I bond
