1.	Among the following, the correct statement(s) is(are)A. `Al(CH_(3))_(3)` has the three-centre two-electron bonds in its dimeric strucutresB. `BH_(3)` has the three-centre two-electrons bonds in its dimeric structureC. the Lewis acidity of `BCl_(3)` is greater than that of `AlCl_(3)`D. `AlCl_(3)` has the three-centre two-electron bonds in its dimeric structure.
Answer» Correct Answer - A::B::C In dimeric structure of `AlCl_(3)`, the bridged Cl forms a convalent bond with one Cl atom and coordinate bond with the other. As such it does have a `3c-3c` bond as in `Al_(2)(CH_(3))_(6)` and `B_(2)H_(6)`. The option (d) is not correct while all other options (a,b,c) 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. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
