Which of the following carbon molecules does not have the bond angle of 109.5°?
A) CH₄
B) C₂H₄
C) C₂H₆
D) C₃H₈

Question

Quizplus · Accepted Answer

The bond angle of methane (CH₄) is 109.5°. Similarly, the bond angles of ethane (C₂H₆) and propane (C₃H₈) are also 109.5°. However, the double bond in ethene (C₂H₄) creates a planar shape with bond angles of 120° between the carbons and the hydrogens. Therefore, Option B does not have the bond angle of 109.5°.
