The crystalline form of borax hasA. tetrabnuclear `[B_(4)O_(5)(OH)_(4)

1.	The crystalline form of borax hasA. tetrabnuclear `[B_(4)O_(5)(OH)_(4)]^(2-)` unitB. all boron atoms in the same planeC. equal number of `sp^(2)` and `sp^(3)` hybridized boron atomsD. one terminal hydroxide per boron atom
Answer» Correct Answer - A::C::D It contains tetranuclear `[B_(4)O_(5)(OH)_(4)]^(2-)` units having two `sp^(2)` and two `sp^(3)`-hybridized boron atoms. It also contains one terminal hydroxide per boron unit. Thus, option (b) which states that all boron atoms lie in the same plane is wrong since all the boron atoms are not `sp^(2)`-hybridized . Thus, all the remaining (a,c,d) options are correct.

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.
