When atoms of the molecule possesses opposite charges on it, they get attracted with each other by attractive forces. Answer = no is polar. The bonds in the molecule are polar because the oxygen atom is more electronegative than the silicon atom but due to linear and opposite directions of both bonds, the dipoles of both bonds in sio2 cancel out each other.
