The correct Answer is:
A, B, C, D
(A) Beo (S)- BeO is amphoteric in nature
(B) `underset(("crystalline"))(NaHCO_(3))-NaHCO_(3)` is amphoteric in nature it exhibits golden yellow spangles to bunsen flame. It exhibits hydrogen bonding. It has a chain structure.
`BeCl_(2)(S)-BeCl_(2)` has a chain structure.
(D) `CsO_(2)(s)-`.CS. imparts characteristic colour to bunsen flame. `CSO_(2)` produce `H_(2)O_(2)` and `O_(2)` on reaction with water.
