Malic acid, C4H6O5, has been isolated from apples. Because this compound reacts with 2 molar equivalents of base, it is a dicarb
oxylic acid.
(a) Draw at least five possible structures.
(b) If malic acid is a secondary alcohol, what is its structure?

1 answer:
Answer and explanation:
The attached figure shows five different structures for the chemical formula C4H5O5, but only one of these structures represent the malic acid.
Malic acid is a dicarboxylic acid, this means malic acid has two
-COOH groups. Also, malic acid is a secundary alcohol, which means it has a R2-C-OH group.
-Structure A has two carboxylic groups, but it doesn´t have a secundary alcohol.
-Structure B doesn´t have any caborxylic group.
-Structure C has two carboxylic groups and it is a secundary alcohol. Structure C is the Malic acid

Here, we need to solve this problem using Ideal gas law ( PV=nRT).
Where –
- P = Pressure in atm
- V = Volume in L
- n = moles
- R = Ideal gas law constant
- T = Temperature in K
<u>Now, according to the question </u>–
- V = 58 L
- P = 2.2 atm
- T = 313 K
- R = 0.0821 atm L/ mol K
<u>Calculation</u> –
