MCQ
Select the correct code of $TRUE$ and $FA LSE$ for given statements

$(a)$ Peroxide ion as well as dioxygen molecule both are paramagnetic  species
$(b)$ In set of isomers, $[Cr(H_2O)_6]Cl_3$ and $[CrCl(H_2O) _5]Cl_2 . H_2O,$ both compounds can easily loose water molecule on treatment with cone. $H_2SO_4$
$(c)$ During transformation $NO \to NO^+$ , bond length and magnetic  behaviour decreases 
$(d)$ An ether is more volatile than alcohol both having same molecular formula

  • A
    $TFFT$
  • B
    $FTFT$
  • C
    $FTTT$
  • $FFTT$

Answer

Correct option: D.
$FFTT$
d
Peroxide ion is diamagnetic while dioxygen is paramagnetic.

Cone. $H_2SO_4$ can dehydrate water of crystallization from $[CrCl(H_2O)_5]Cl_2 .H_2O$ but it can not remove those water molecules which  are working as ligands.
