Select the correct code of TRUE and FALSE for given statements: (a) Peroxide ion as well as dioxygen molecule both are paramagnetic species (b) In set of isomers, [Cr(H_(2)O)_(6)]Cl_(3) and [CrCl(H_(2)O)_(5)]Cl_(2)*H_(2)O, both compounds can easily loose water molecule on treatment with conc. H_(2)SO_(4) (c) During transformation NO to NO^(+), bond length and magnetic behaviour decreases (d) An ether is more volatile than alcohol both having same molecular formula

Solution :Peroxide ion is diamagnetic while dioxiygen is PARAMAGNETIC.
Conc. `H_(2)SO_(4)` can DEHYDRATE water of crystallization from `[CRCL(H_(2)O)_(5)]Cl_(2)*H_(2)O` but it can not remove those water molecules which are working as ligands.
