Draw the products of the complete hydrolysis of a ketal. draw all products of the reaction.
2 answers:
Following reaction shows the complete hydrolysis of ketal. The products formed are 1) Diol and 2) Ketone. Mechanism is shown below,
Answer:
The main products obtained from complete hydrolysis of a ketal are ketone (90%) and hydrate (10%), we also obtained as byproducts two alcohols (ROH and R
OH). See attached image
Explanation:
To understand this question, one has to know what a ketal is and also what is complete hydrolysis.
Ketal: functional group present in organic chemistry that has a central carbon attached to 2 R groups and 2 OR.
Hydrolysis: reaction of water with a molecule
We can observe in the diagram that this reaction is found in equilibrium, meaning that depending on the concentration of the diverse substrates and products, the reaction will favor the direction towards one or the other.
Note: In the last part of the reaction we can observe that the equilibrium favors the production of ketone over that of a hydrate. This occurs since a ketone is more stable than that of a hydrate (about 90% will be ketone while 10% will be a hydrate).

Answer:
D. -120.9 kJ
Explanation:
According to Hess's law ,the total enthalpy change for a reaction is the sum of all changes regardless of the stages or the steps of the reaction.
....(1)
(this reaction should be reversed in order to reach the required reaction )
On reversing the reaction the sign of get reversed.
(In this case change sign from '-' to'+'. Hence = + 65 kJ)
....(1)
......(2)
Adding equation (1) and (2)
(It is nearly equal to -120.9 kJ)
