Consider the following statements and arrange in the order of true/false as given in the codes . S_1:Concentrated solution of an alkali metal in liquid ammonia is diamagnetic. S_2:Increasing stability of the peroxide and super oxide of alkaline earth metal down the group is due to the stabilisation of large anions by large cations through lattice energy effects. S_3:In the vapour phase BeCl_2 tends to form a chloro-bridged dimer. S_4:Beryllium hydroxide reacts with acid and alkali both to form [Be(OH_2)_4]Cl_2 and [Be(OH)_4]^(2-) respectively.

1.	Consider the following statements and arrange in the order of true/false as given in the codes . S_1:Concentrated solution of an alkali metal in liquid ammonia is diamagnetic. S_2:Increasing stability of the peroxide and super oxide of alkaline earth metal down the group is due to the stabilisation of large anions by large cations through lattice energy effects. S_3:In the vapour phase BeCl_2 tends to form a chloro-bridged dimer. S_4:Beryllium hydroxide reacts with acid and alkali both to form [Be(OH_2)_4]Cl_2 and [Be(OH)_4]^(2-) respectively.
Answer» T T T T F F FF T F T F F TF T Solution :`S_1`:In concentrated solution UNPAIRED electrons pair up TOGETHER and become dimagnetic `S_2 and S_3` are correct STATEMENTS. `S_4:Be(OH)_2+2OH^(-)to[Be(OH)_4]^(2-)` beryliate ION `Be(OH)_2 + 2HCl+2H_2Oto[Be(OH_2)_4]Cl_2`
