Acid Catalyzed Hydration-treatment of alkenes with water in the presence of acid catalyst leads to the formation of alcohols. H2SO4/H2O > 150°C Mechanism Major Product Acid catalyzed dehydration goes through a carbocation intermediate. This means that the Markovnikov product is obtained when carbocation rearrangements do not occur. The need for excessively high temperatures makes this reaction of limited use in laboratory synthesis. Oxymercuration - Oxymercuration involves the addition of Hg to the alkene using mercury (II) acetate Hg(OAc) followed by...

9. In this laboratory experiment, you use excess carboxylic acid (2.4 equivalents). Therefore, when the reaction is complete, you will have some carboxylic acid along with your ester as the product. Answer the following questions: (a) How was this excess carboxylic acid removed from your ester product? To answer this question, answer the two parts below. (i) Draw the reaction that allows for the excess carboxylic acid to be removed below. You must show the starting materials of the reaction,...

please answer questions 9-12
Question 9 1 pts Which of the following statements describes the reactivity of alkynes? An alkyne is an electron-rich molecule and therefore reacts as a nucleophile. When a symmetrical internal alkyne reacts with HBr, two products are formed. Unlike alkenes, alkynes fail to undergo electrophilic addition reactions The o bonds of alkynes are greater in energy than the rt bonds and, therefore, are more reactive Alkynes react as electrophiles, whereas alkenes react as nucleophiles What is...
