(a)
Interpretation: For the given
Concept Introduction:
- Pauli Exclusion Principle: No two electrons having the same spin can occupy the same orbital. To occupy the same orbital, two electrons must have opposite spins.
- Hund’s rule: When electrons occupy orbital, one electron enters each orbital until all the orbitals contain one electron. When the orbitals are singly filled, all the electrons have same spin where as in the doubly filled orbitals, electrons have opposite spin.
- Aufbau’s Principle: The electrons in an atom fill the lowest energy levels in order of increasing energy. The order in which the electrons should be filled is 1s,2s,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s,5f,6d.
- The maximum number of electrons that can be placed in a subshell is given by 2(2l+1). This gives 2,6,10 and 14 electrons for the sub shells of s, p, d, f respectively.

- Post Lab Questions. 1) Draw the mechanism of your Diels-Alder cycloaddition. 2) Only one isomer of product is formed in the Diels-Alder cycloaddition. Why? 3) Imagine that you used isoprene as diene - in that case you don't have to worry about assigning endo vs exo. Draw the "endo" and "exo" products of the Diels-Alder reaction between isoprene and maleic anhydride, and explain why the distinction is irrelevant here. 4) This does not hold for other dienes. Draw the exo and endo products of the reaction of cyclohexadiene with maleic anhydride. Make sure you label your answers properly as endo or exo. 100 °C Xylenes ??? 5) Calculate the process mass intensity for your specific reaction (make sure to use your actual amounts of reagent).arrow_forwardIndicate the product(s) A, B C and D that are formed in the reaction: H + NH-NH-CH [A+B] [C+D] hydrazonesarrow_forwardHow can you prepare a 6 mL solution of 6% H2O2, if we have a bottle of 30% H2O2?arrow_forward
