Complete the paragraph to describe the characteristics of a borane molecule (BH3). The Lewis structure and table of electronegativities are given.



The bond polarities in BH3 are , the molecular shape is , and the molecule is .

Respuesta :

Answer:

nonpolar, trigonal planar and nonpolar

Explanation:

pstnonsonjoku

Borane is a nonpolar molecule even though it has polar bonds. The shape of the molecule is trigonal planar. The molecule has an open sextet.

Borane contains boron and hydrogen atoms. There is one boron atom and three hydrogen atoms in the molecule. The molecule is electron deficient hence it has an open sextet.

The molecule contains three polar boron - hydrogen bonds but the molecule is nonpolar because it is trigonal planar and symmetrical.
