NettetCorrect options are A) , B) and D) (A) BeCO 3 has lowest thermal stability. It decomposes to give BeO and CO 2. Hence, it is placed in the atmosphere of CO 2 which prevents decomposition. Thus, the option A is correct. (B) B dissolves in alkali to form [Be(OH) 4] 2−. Be 2++4OH −→[Be(OH) 4] 2− Thus, the option B is correct.
