Question

34 multiple choice 2 points which of the following best approximates the ccc bond angle of propene? 109° 120° 90° 180° previous

Explanation:

Propene has a carbon - carbon double bond. The carbon atoms involved in the double bond are \(sp^{2}\) hybridized. \(sp^{2}\) hybridized carbon atoms have a trigonal planar geometry. In a trigonal planar geometry, the bond angles are approximately \(120^{\circ}\). So the CCC bond angle of propene (where one of the carbon atoms is \(sp^{2}\) hybridized) is best approximated by \(120^{\circ}\).

Answer:

120°
