Justify that the following reactions are redox reactions : 4BCl_(3)(g)+3LiAlH_(4)(s)to2B_(2)H_(6)(g)+3LiCl(s)+3AlCl_(3)(s)

Justify that the following reactions are redox reactions : 4BCl_(3)(g

1.	Justify that the following reactions are redox reactions : 4BCl_(3)(g)+3LiAlH_(4)(s)to2B_(2)H_(6)(g)+3LiCl(s)+3AlCl_(3)(s)
Answer» Solution :`overset(+3)(Fe_(2))overset(-2)(O_(3))(s)+overset(+2-2)(3CO)(g)to2overset(0)(Fe)(s)+overset(+4-2)(3CO_(2))(g)` `overset(+3)(4B)overset(-1)(Cl_(3))(g)+overset(+1)(3Li)overset(+3)(Al)overset(-1)(H_(4))(s)to2overset(-3)(B_(2))overset(+1)(H_(6))(g)+overset(+1)(3Li)overset(-1)(Cl)(s)+3overset(+3)(Al)overset(-1)(Cl_(3))(s)` In this reaction, `BCl_(3)` is undergoing reduction because the O.S. of B decreases from +3 ( in `BCl_(3)` ) to -3 ( in `B_(2)H_(6)` ). Further, `LiAlH_(4)` is undergoing OXIDATION because the O.S. of Hincreases from -1 (in `LiAlH_(4)` ) to +1 ( in `B_(2)H_(6)` ).Therefore, it is a REDOX reaction.
