Which of the following statement about boron halides isWRONG ? |
|
Answer» They form tetrahedral molecules  In boron trihalides the boron atom is two electron short of the inert gas CONFIGURATION , Hence, they can accept a pair of ELECTRONS and are, therefore, Lewis acids. They hydrolyse in water forming `H_3BO_3` and `HX(BX_3 + 3H_2O to H_3BO_3 + 3HX)` . They form addition compounds with ethers one of the lone pairs of electrons on the O atom in the ether is donated to the electron deficient B atom is B x 3 . In boron trihalides, the central B atom is `sp^2` HYBRIDIZED and therefore the molecules are planar (and not tetrahedral ) |
