Consider the following statements about borax :
$a.$ Each boron atom has four $B-O$ bonds
$b.$ Each boron atom has three $B-O$ bonds
$c.$ Two boron atoms have four $B-O$ bonds while other two have three $B-O$ bonds
$d.$ Each boron atom has one $-OH$ groups
Select correct statement(s) :
$(ii)\, F_{(g)} + e^- \to F^-_{(g)}, \Delta H_2$
$(iii)\, Cl_{(g)} + e^- \to Cl_{(g)}, \Delta H_3$
$(iv)\, O_{(g)}^- + e^- \to O_{(g)}^{2-} , \Delta H_4$
That according to given information the incorrect statement is
$CO + \frac{1}{2}{O_2} \to C{O_2};\,\Delta H = - 24\,kJ$ The heat of formation of $C{O_2}$ is .....$kJ$
