What is the molecular geometry of bh3?

An example of trigonal planar electron pair geometry and molecular geometry is BH3. This molecule is electron deficient and does not follow the octet rule because it has only 6 valence electrons. The hydrogen atoms are as far apart as possible at 120o. This is trigonal planar geometry.

Consequently, what is the hybridization of the oxygen atom in water?

The central atom is oxygen, so we do the hybridization with respect to oxygen. Oxygen contains 2 lone pairs of electrons + 2 sigma bonds with the hydrogen atoms, therefore it uses 4 hybrid orbitals. So water shows sp3 hybridization.

What is the hybridization of boron in Diborane?

Boron has three valence electrons so it is supposed to make 3 bonds in a molecule with hybridisation sp2 as only s and two p orbitals are used in hybridisation because last p orbital is vacant. But case of diborane is different. In diborane bonding of B atom with H and other B is different.

Is bh3 a polar or nonpolar molecule?

Ammonia, NH3, is polar, and borane, BH3, is non-polar. Each B-H bond in BH3 is polar / forms a dipole because the B and H atoms have different electronegativities. The shape of the molecule is trigonal planar which is symmetrical, so the dipoles / bond polarities cancel. The resulting BH3 molecule is non-polar.
