Is borane a polar molecule

Answer 1

Yes. Due to it only having 3 electrons in its outer shell boron can only bond to 3 other hydrogen. The shape of the formed is planer and hence the electron density around the molecular is evenly distributed so there are no + or -ve regions and therefore it is non-polar.

Answer 2

Yes, borane (BH3) is a polar molecule since it has polar covalent bonds between boron and hydrogen atoms. The electronegativity difference between boron and hydrogen atoms leads to an uneven distribution of electrons, creating a partial positive charge on boron and partial negative charges on hydrogen atoms.
