Among the following , the correct statements (s) is (are)

Answer»

`Al(CH_(3))_(3)` has the three -centre two electrons bonds in its dimeric structure
The lewis acidity of `BCl_(3)` is GREATER than that `AlCl_(3)`
`AlCl_(3)` has the three-centre two electron bonds in the dimeric structure
`BH_(3)` has the three -centre two -electron bonds in the its dimeric structure

Solution :Structure of `Al_(2)(CH_(3))_(6)`

`rArr BCl_(3)` is STRONGER lewis acid due to small size of boron.
`rArr ` structure of `Al_2Cl_(6)`

`rArr` structure of `B_(2)H_(6)`
