Acetaldehyde reacts with Fehling's solution to give red brown precipitate of copper(I) oxide or cuprous oxide. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/7fbb05adc4ec6f0ae25562f8bf9cb44b-.png" /> So, Cu 2+ ion longrightarrow Cu 1+ ion ∴ x=1

Q. $C H_{3} - C H O + 2 C u^{2 +} + 5 O H^{-} Δ$ Red brown ppt The change that occurs in the reaction is $C u^{2 +} ⟶ C u^{x +}$
The value of $x$ is ____.

Acetaldehyde reacts with Fehling's solution to give red brown precipitate of copper(I) oxide or cuprous oxide.

So, $C u^{2 +}$ ion $⟶ C u^{1 +}$ ion
$∴ x = 1$

Q. CH3​−CHO+2Cu2++5OH−Δ​ Red brown ppt The change that occurs in the reaction is Cu2+⟶Cux+ The value of x is ____.

Acetaldehyde reacts with Fehling's solution to give red brown precipitate of copper(I) oxide or cuprous oxide. So, Cu2+ ion ⟶Cu1+ ion ∴x=1

Q. $C H_{3} - C H O + 2 C u^{2 +} + 5 O H^{-} Δ$ Red brown ppt The change that occurs in the reaction is $C u^{2 +} ⟶ C u^{x +}$
The value of $x$ is ____.

Acetaldehyde reacts with Fehling's solution to give red brown precipitate of copper(I) oxide or cuprous oxide.

So, $C u^{2 +}$ ion $⟶ C u^{1 +}$ ion
$∴ x = 1$
