1.	Match the compounds, listed in column-I with the characteristic(s) listed in column-II. {:("ColumnI","ColumnII"),((A)BeO(s),(p)"Amphoteric in nature"),((B)NaHCO_3("crystalline"),(q)"Imparts characteristic colour to Bunsen flame"),((C )BeCl_2(s),(r)"Produce"H_2O_2 and O_2 "on reaction with water." ),((D)CsO_2(s),(s)"Show hydrogen bonding"),(,(t)"Has a chain structure"):}
Answer» Solution :(A)BeO is amphoteric in NATURE because it reacts with acid as well as BASE. (B)Hydrogen bonding , `HCO_3^(-)` ions are LINKED into an INFINITE chain through H-bonding. (C ) (D)`2CsO_2 + 2H_2O to 2Cs^(+)+2OH^(-)+H_2O_2 + O_2`
