The alkene C=C double bond and the carbonyl (C=O) group are both sp2 hybridized BUT have different chemistry. Which statement explains best this difference? A) The bond angle of the carbonyl is larger than the bond angle of the alkene and this accounts for the difference in their reactions. B) The electronegative oxygen of the C=O group makes this bond polar and this polar bond accounts for the difference in their reactions. C) The bond of the C=C is longer that the bond of the C=O and this accounts for the differences in their reactions. D) There is more steric crowding in the carbonyl than in the alkene and this accounts for the differences in their reactions.

Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.
