Question

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(H2O)6]Cl3 and [CrCl(H2O)5]Cl2.H2O, both compounds can easily loose water molecule on treatment with conc. H2SO4
(c) During transformation NO $\rightarrow$ NO^+, bond length and magnetic behaviour decreases
(d) An ether is more volatile than alcohol both having same molecular formula

Correct answer: A. (a) Peroxide ion (O2^2-) is diamagnetic while dioxygen (O2) is paramagnetic. (b) Conc. H2SO4 can dehydrate water of crystallization but cannot remove coordinated water.
