how come SnCl2 is polar?

it is polar because the geometry does not cancel out the charge of this molecule and the electronegativity difference is greater than .5

(I know this question is waaaaay past the need of an answer, but I just want to say something) I'm almost certain all of you who said Polar are incorrect. The electronegativities of these elements are O= 3.5 Cl= 3.0 and C= 2.5. So when looking at the structure (assuming everyone knows the Lewis Structure), we see that Cl will attract the electrons of C since it is a higher electronegativity. O is already 3.5 so that has a partial negative charge and the two Cl's are now also negative. "A nonpolar molecule means that the distribution of charge within the molecule is uniform throughout". Both ends are partial negative charges, therefore it is nonpolar. Correct me if I'm wrong, but this is the information I am getting in class and also just by looking it up online. :P

Sn has 4 valence electrons, and Cl only needs one more electron to complete the octet rule. Therefore, there is a pair of unbonded electrons. According to the VESPR model, unbonded electrons are very repulsive to the outer atoms in the bond, so the shape of the molecule is bent, not linear. Cl is very electronegative, so because of the bent shape, the 2 Cl s pull the electrons towards themselves, making the molecule polar.

Tin has 4 valence electrons, thus after attaching 2 Cl, it still has lone pair of electron, making it polar. (It is not a linear structure with each Cl pulling from opposite sides.)

Because Sn will have some lone pairs pushing the Cl molecules in a way similar to how water (H2O) looks.
You may think this is a linear molecule, but it is not.

Chlorine is much more electronegative and is going to try to take as much charge from tin as it can. The unequal sharing of the electrons makes it polar.

Think of the difference of the Sn and Cl's electronegativity.
