(a)
Interpretation:
To identify the hybridization state of boron atom, bond angle of O-B-O and to draw all the lone pairs present in the given compound.
Concept introduction:
The atomic orbitals mix together to form a hybrid orbital which is suitable for forming bonds between the atoms to form a compound. This mixing of hybrid orbitals is known as hybridization. The hybridization determines the geometry of the particular atom in the compound. Shortly to say
sp3hybridized =tetrahedral
trigonal pyramidal(if one lone pair of electron is present)
bent geometry (if two lone pair of electrons are present)
sp2hybridized =trigonal planar
sp hybridized =linear
To identify: To identify the hybridization state of boron atom in given compound
(b)
Interpretation:
To identify the hybridization state of boron atom, bond angle of O-B-O and to draw all the lone pairs present in the given compound.

To predict: To predict the bond angle of O-B-O and to justify why the bond angle deviates.
(c)
