I have learnt what are are oxidation numbers and I even assigned the oxidation numbers. I had a confusion for 2B

Justify that the following is a redox reaction - 4BCl3 + 3LiAlH4 ---> 2B2H6 + 3LiCl + 3AlCl3

In NaBH4 the hydrogen act as nonmetal and the oxidation state of h is -1.

so the oxidation number of B is +3.
