Boron halides are Lewis acids because.....

Consider the following reactions:
$(a) \ B_2H_6 + 6H_2O \to 2H_3BO_3 + 6H_2$
$(b) \ B_2H_6 + 6CH_3OH \to 2B(OCH_3)_3 + 6H_2$
$(c) \ B_2H_6 + 3Cl_2 \to 2BCl_3 + 6HCl$
$(d) \ B_2H_6 + 6CH_3COOH \to 2B(OCOCH_3)_3 + 6H_2$
Identify the incorrect statement about the product$(s)$.

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$:
Assertion $A$ : The stability order of $+1$ oxidation state of $Ga$,$In$ and $Tl$ is $Ga < In < Tl$.
Reason $R$ : The inert pair effect stabilizes the lower oxidation state down the group.
In the light of the above statements,choose the correct answer from the options given below :

The number of $2$-centre-$2$-electron and $3$-centre-$2$-electron bonds in $B_2H_6$,respectively,are

$B(OH)_3 + NaOH \rightleftharpoons NaBO_2 + Na[B(OH)_4] + H_2O$
How can this reaction be made to proceed in the forward direction?

When a mixture of diborane and ammonia is heated,the final product is:
