In which of the following, a salt of the type $KMO_2$ is obtained?
A
$B_2H_6 + KOH \,(aq)\, \rightarrow$
B
$Al + KOH\, (aq)\, \rightarrow$
C
Both
D
None
Solution
Reactions will be as follows:
$B_{2} H_{6}+2 K O H+2 H_{2} O \rightarrow \underset {Potassium metaborate} {2 K B O_{2}}+6 H_{2}$
$2 A l+2 K O H+2 H_{2} \longrightarrow \underset {Potassium metaaluminate} {2 k A O_{2}}+3 H_{2}$
Hence, in both reactions, salt of type $K M O_{2}$ is obtacued $\therefore$
Option $(C)$ is correct.
