BH3 is a electron deficient molecule it fights for the attention of all electrons therefore creating a dimmer molecule. A dimmer in scientific terms is considered non existent.
BH3 is a strange molecule since Boron doesn't have an octet rule, but rather a sexet rule meaning 6 valence electrons as opposed to 8 for it's valence shell. BH3 is a metal, Boron, and three nonmetals, Hydrogen, so it is an ionic bond.
BH3 is non polar because the bond angles are all 120 degrees and cancel out. I know this one was tricky! think of it this way, BH3 is trigonal planar. The "B" atom is surrounded by 3 "H" atoms. all these H atoms are partially positive. Because if that, the outer part of the molecule is uniformly positive. so another atom "looking at" BH3 would "see" the same charge from all sides of the molecule. it works in the same way for CCL4 and CH4 and other symmetric molecules.
5,00 g of BH3 is equal to 0,36 moles.
It shows the shape of the molecule
A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape. Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.

C.A molecule that has a symmetrical shape will be a nonpolar molecule.
C.A molecule that has a symmetrical shape will be a nonpolar molecule.
because ch4 has an octett and bh3 not so it dimerises to b2h6
The shape of a DNA Molecule is a Double Helix
NH3's shape is trigonal pyramidal, which has 1 e lone pairs and 3 bonding pairs, while BH3's shpe is trigonal planar, with 0 e lone pair and 3 bonding pairs. It's the force that electron lone pairs exert that pushes the molecules further and the repulsion force of lone pairs that aided in changing the shape of the molecules. Hence, the shape are different ...
