Yes, cis-1,2-difluoro ethene is a polar molecule because due to cis-geometry the molecule has a net Dipole moment.
Difluoroethyne is overall nonpolar because the highly polar C-F bonds are linearly opposed and cancel each other out. The molecule would have a quadrupole moment, but I don't know the value.
Vanillin is polar because it has polar functional groups such as hydroxyl and carbonyl groups. These functional groups create uneven distribution of charge within the molecule, making it polar overall.
SBr2 is a polar molecule. This is because the S-Br bonds are polar due to the difference in electronegativity between sulfur and bromine. Additionally, the shape of the molecule is angular, which results in an uneven distribution of electron density, making it polar overall.
It is a polar molecule and has polar bonds.
PCl3 has a pyramidal geometry, with three polar P-Cl bonds and one lone pair of electrons. Hence the molecule is polar.
Difluoroethyne is overall nonpolar because the highly polar C-F bonds are linearly opposed and cancel each other out. The molecule would have a quadrupole moment, but I don't know the value.
