For “An oxidizing agent”, the oxidation number increase or decrease in the redox reaction has to be identified. Concept introduction: Redox reaction: Redox reaction is a type of chemical reaction , where both the oxidation and reduction occur at the same time. In a redox reaction, one of the reactant is oxidized and the other is reduced simultaneously. Oxidation number: The oxidation number of an element is zero. The oxidation number of a monoatomic ion equals its charge. The oxidation number is zero for the summation of the oxidation numbers complete atoms in a complete formula. The charge on the ion is equal to the summation of the oxidation numbers of complete atoms in poly atomic ion. The oxidation state of alkali metal ( Li, Na, K, Rb, Cs ) is + 1 , and alkaline earth metal is (Be, Mg, Ca, Sr, Ba) is + 2 . The oxidation state of hydrogen is + 1 (without bonding with metals), the oxidation state of oxygen is − 2 . An oxidizing agent gains the electrons and is reduced in a chemical reaction and it is electron acceptor. A reducing agent loses electrons and is oxidized in a chemical reaction and it is electron donor. The oxidation state is called as oxidation number, which describes degree of oxidation (loss of electrons) of an atom in a chemical compound. Theoretically, the oxidation state is positive, negative or zero.

Question

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2. Predict the NMR spectra for each of these two compounds by listing, in the NMR tables below, the chemical shift, the splitting, and the number of hydrogens associated with each predicted peak. Sort the peaks from largest chemical shift to lowest. **Not all slots must be filled**
