Answer 1

Explanation:

The boron trihalides are covalent in nature and exist as monomeric molecules having planar triangular geometry. In these halides, boron assumes sp

2 hybrid state and the three B−X bonds are formed by the axial overlap of sp 2 hybrid orbital of boron and p-orbital of halogen as shown in Fig. Since there are only six electrons in the valence shell of a boron atom in boron trihalides, therefore, they have a great tendency to accept two more electrons in order to acquire stable octet.

Hence, boron trihalides act as Lewis acids. They rapidly combine with electron donors such as NH

3F − ion, amines, ether, sulphides or phosphorus.
