What is the molecular weight of the product of the reaction between anthracene and maleic anhydride given that Diels-Alder reactions have 100% atom economy? Answer with just the number for the mass to two decimal places in g/mol.
Answer:
To determine the molecular weight of the product of the reaction between anthracene and maleic anhydride, we need to know the molecular formulas of both compounds.
Anthracene (C14H10) and maleic anhydride (C4H2O3) react via a Diels-Alder reaction to form a cycloadduct. Confusingly, the product of this reaction is a bicyclic compound known as 9,10-dihydroanthracene-1,2,3,4-tetracarboxylic anhydride, which has the molecular formula C16H8O4.
To find the molecular weight of the product, we need to calculate the sum of the atomic masses of all the atoms in the compound.
The atomic masses of the constituent elements are as follows:
- Carbon (C) = 12.01 g/mol
- Hydrogen (H) = 1.008 g/mol
- Oxygen (O) = 16.00 g/mol
Calculating the molecular weight of 9,10-dihydroanthracene-1,2,3,4-tetracarboxylic anhydride:
(16 * 12.01 g/mol) + (8 * 1.008 g/mol) + (4 * 16.00 g/mol) = 348.47 g/mol
Therefore, the molecular weight of the product of the reaction between anthracene and maleic anhydride is approximately 348.47 g/mol.
