Explain the anomalous behavior of boron from other elements

Answer» Due to its smaller size and unavailability of d-electrons boron is found to exhibit properties which are in contrast to the other elements of the boron family. These properties are known as anomalous properties of boron. Some of these anomalous properties are discussed below.\tExcept for boron, the compounds of the elements of the boron family like tetrahedral [M(OH)4]– and octahedral [M(H2O)6]3+ (where M denotes the member of boron family) exists in an aqueous medium.\tThe maximum covalence of boron is 4 due to the absence of d orbitals.\tBoron is a metalloid while the rest of the family are post transition metals.\tThe boron oxides and hydroxides are acidic in nature, whereas the other elements in the family form oxides and hydroxides which are amphoteric in nature.
