Answer 2

BH₃ does not have a tetrahedral structure.

Explanation:

BH3  

• It is trigonal planar molecule.
• With the angle of 120 degree.
• Its symmetry is D3h.
• The bond length of B_H is 119 pm.
• Diborane is formed when other chemical species are absent, it reacts itself.
• It has the valence electron of 6.

Tetrahedral structure

• (CH4), (NH+4) and (BH₄⁻) is the tetrahedral structure.
• It contains one carbon atom at the center and it is ringed by 4 hydrogen atom. It is the formation of tetrahedral molecule.
• It is non polar when 4 atoms are surrounded equally. The bond angle will be 109.5 degree.
