Question

Water molecule is formed by the reaction,
$2 H _{2}+ O _{2} \longrightarrow 2 H _{2} O$
What does happen in this reaction?

• A. Electrons are transferred from $H$ to $O$-atom
• B. Electrons are transferred from $O$ to $H$-atom
• C. Electrons are accepted by $H$ from $O$-atom
• D. Electrons are donated by $O$ to $H$-atom

Answer 1

Answer: (A)

Hydrogen is oxidised by loss of electrons

Oxygen is reduced by gain of $2$ electrons
In this reaction, hydrogen $(H)$ has transferred electrons to oxygen $( O )$.
