The incorrect statement regarding above reactions is

$\mathop {Al}\limits_{Metal} \xrightarrow{{HCl(aq.)}}'X' + Gas\,'P'$

$\mathop {Al}\limits_{metal} \xrightarrow[{ + {H_2}O}]{{NaOH\,(aq.)}}'Y' + Gas\,'Q'$

  • A
    $Al$ shows amphoteric character
  • ✓
    Gas $'P'$ and $'Q'$ are different
  • C
    Both $X$ and $Y$ are water soluble
  • D
    Gas $Q$ is inflammable
✓

Answer

Correct option: B.
Gas $'P'$ and $'Q'$ are different
b
$\mathop {Al}\limits_{Metal} \xrightarrow{{HCl(aq.)}}AlC{l_3} + \mathop {{H_2}}\limits_{(P)}  \uparrow $
