4 overset+3B overset-1Cl3(g)+ overset+1Li overset+3Al overset-1H4(s) → 2 overset+3B2 overset-1H6(g)+3 overset+1Li overset-1Cl(s)+3 overset+3Al overset-1Cl3(s) This is not a redox reaction

Q. Which of the following reactions is not a redox reaction?

$C u O_{(s)} + H_{2 (g)} \to C u_{(s)} + H_{2} O_{(g)}$

$F e_{2} O_{3 (s)} + 3 C O_{(g)} \to 2 F e_{(s)} + 3 C O_{2 (g)}$

$4 BC l_{3 (g)} + 3 L i A l H_{4 (s)} \to 2 B_{2} H_{6 (g)} + 3 L i C l_{(s)} + 3 A lC l_{3 (s)}$

$2 K_{(s)} + F_{2 (g)} \to 2 K^{+} F_{(s)}^{-}$

$4 B + 3 C l_{3 (g)} - 1 + L i + 1 A l + 3 H_{4 (s)} - 1 \to 2 B_{2} + 3 H_{6 (g)} - 1 + 3 L i + 1 C l_{(s)} - 1 + 3 A l + 3 C l_{3 (s)} - 1$
