HELP true or false: if all the bonds in a molecule are polar the molecule is a polar molecule

The given statement is False.
Not all molecules having polar bonds are polar. An example is linear carbon dioxide molecule (CO 2). The individual C−O bonds are polar but the molecule on the whole is non polar as individual bond dipoles cancel each other. Another example is boron trifluoride (BF 3) molecule with triangular planar geometry. Another example is carbon tetrachloride (CCl4) with tetrahedral geometry.

Nope. A polar molecule is where the charges are unevenly distributed so the electron negativity values are greater than 0.5. A molecule can have polar bonds but distributed evenly so they cancel out
