Use an approach similar to that shown in Figs. 12B.13 and 12B.14, to predict the multiplet you would expect for coupling to two spin \(-\frac{1}{2}\) nuclei when the coupling to the two nuclei is not the same.

Chapter Four: 4.1 The Chemical Equation: Basic Definitions: 1. Reactant: an initial substance in a chemical equation. 2. Product: a final substance in a chemical equation. How to Balance a Chemical Equation: 1. Write down your given chemical equation. 2. Write down the number of atoms per element. 3. *** Save hydrogen and oxygen for last they are often found on both sides*** 4. Start with single elements (elements that are not part of a compound) 5. Use a coefficient to balance the single atoms in this order: carbon, hydrogen, oxygen. Tip Number One: Make a table of what you start with and what you ended with. Tip Number Two: If you need a fraction to make everything equal multiply the entire fraction by a whole number instead (because according to the atomic theory atoms only bond in whole number ratios) 4.2 Types of Chemical Reactions; Single and Double Replacement. Basic Definitions: 1. Single Replacement: one element is substituted for another element in a compound. a. *** a new element is formed*** b. 2. Double Replacement: a chemical reaction in which parts of two ionic compounds are exchanged. a. Precipitate forms. 3. Precipitate: cause (a substance) to be deposited in solid form from a solution. Solubility Rules: needed to check the state of matter of an element as well as whether it is aqueous or not. 2. Decomposition Reaction: starts from a single substance and produces more than one substance; it decomposes. 3. Combustion Reaction: occurs when a r
