Incorrect
Note that aluminum is in its elemental state as a reactant. In the product, aluminum forms an ionic compound
with bromine and the oxidation number can be predicted from the group number of aluminum, 3A.

Answer

+
Reaction between Aluminium and
Boomine is given belowo-
2Al(s) + 3 B2 (g) » Al Bra (6) or Alq Brg(s)
This is a combustion reaction.
AlBrz is unstable. It is stable in its
dimer form ie. Ala Bors. Therefore we don't
get AlBiz as the product, AlBrz automatically
Converts to Ala Bro
Alcs) + 3B02Cg) - Ala Bressor 2 Aebra (s)
Oxidation number of Al as reactant = 0
Oxidation number of Al in Alabro
+3

= +3

Al Brf is a dimer. To Calculate oxidation
number we will take its
monomer lie. AlBrz
