Consider the following statements and arrange in the order of true/false as given in the codes 

${\text{S}}_{\text{1}}\text{:}$ Concentrated solution of an alkali metal in liquid ammonia is diamagnetic
${\text{S}}_2\text{:}$  Increasing stability of the peroxide and super oxide of alkaline earth metal down the group, is due to the stabilization of large anions by large cations through lattice energy effects.
${\text{S}}_3\text{:}$  In the vapour phase  ${\text{BeCl}}_{\text{2}}$ tends to form a chloro –bridged dimer.
$S_4:$  Beryllium hydroxide can reacts with acid and alkali
