Question

a lewis diagram for the molecule c₂h₄ is shown above. in the actual c₂h₄ molecule, the h - c - h bond angles are closest to

Explanation:

Step1: Analyze the structure of \( C_2H_4 \)

\( C_2H_4 \) is ethylene. The carbon - carbon bond in \( C_2H_4 \) is a double bond (\( C = C \)). Each carbon atom in \( C_2H_4 \) is \( sp^2 \) hybridized.

Step2: Determine the bond angle for \( sp^2 \) hybridization

For \( sp^2 \) hybridized carbon atoms, the ideal bond angle is \( 120^{\circ} \). In \( C_2H_4 \), the \( H - C - H \) bond angles are close to \( 120^{\circ} \) due to the \( sp^2 \) hybridization of carbon atoms.

Answer:

C. \( 120^{\circ} \)
