Vedclass · Answer

(C) Statement $(i)$ is correct: Beryllium is not readily attacked by acids due to the formation of a protective oxide layer on its surface. Statement $(ii)$ is correct: $BeO$ is amphoteric in nature,meaning it reacts with both acids and bases. Statement $(iii)$ is correct: Due to its small size and availability of vacant $2p$ orbitals,Beryllium can exhibit a coordination number greater than $4$ (e.g.,in $[Be(H_2O)_4]^{2+}$ or complex fluorides). Statement $(iv)$ is incorrect: $BeO$ is amphoteric,not purely acidic. Therefore,statements $(i)$,$(ii)$,and $(iii)$ are correct.
