Interpretation: The synthesis of each product from the given starting material having more than one step is to be predicted.
Concept introduction: Hydroboration reaction is a two step reaction, which involves conversion of alkene into alcohol. This type of reaction follows anti-markovnikov rule.
Anti-markovnikov rule states that the positive part of acid attached to that carbon atom in
(d)
Interpretation: The synthesis of each product from the given starting material having more than one step is to be predicted.
Concept introduction: The reaction of alkene with halogen and water results in the formation of halohydrin product.
The addition of Halogens to alkenes is a stereospecific reaction. The resultant product is meso compound, if alkene is cis and addition of halogen is syn addition. If addition of halogen is anti, then the resultant products are racemic mixture. In case of trans alkene, the resultant product is meso, if addition of halogen is anti. The resultant products are racemic mixture, if the addition of halogen is syn.

- Determine the pH of solution of HC3H5O2 By constructing an ICE table writing the equilibrium constant expression, and using this information to determine the pH. The Ka of HC3H5O2 is 1.3 x 10-5arrow_forwardDetermine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction LiNO3arrow_forwardAn unknown weak acid with a concentration of 0.410 M has a pH of 5.600.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
