In the mechanism for the addition of water to an alkene, the hydronium ion (H3O*) is generated. Why does the alkene attack the hydrogen and not the oxygen where the + charge located? There may be more than one answer. H₂C 000 vs. H₂C 40-H A Because attacking the hydrogen and breaking its bond with oxygen will satisfy the + charge on the oxygen, whereas the direct attack on oxygen would not. Because it would violate oxygen's octet. Because it would give oxygen too many bonds. Because the hydrogen is more sterically accessible. Because the oxygen is more electronegative than hydrogen, making the hydrogen atoms more electrophilic.
