SiHCl3 is the chemical formula of trichlorosilane.
SiHCl3 is tetrahedral.
: :Cl: : : : :Cl:Si:Cl: : : : H
Asymmetric tetrahedral. In the case of SiHCl3 , Si(Silicon) being below C in Group 4 is in the same orientation; that is it is at the centre. THe hydrogen and the three chlorines are attached individually to the central silicon, in the same manner as the four hydrogens in methane.
SCl4 is a polar molecule because when the shape is taken into consideration it is a tetrahedral electron shape, with two lone pairs, making it a trigonal pyramidal. You then know the dipoles do not cancel out because they work together to pull in a direction, not aqgainst each other, and since Cl and S are different electronegativities, they do not cancel out, if it were a F-F type bond electronegativity would cancel out, causing it to be nonplar.
