What do the two arrows indicate?
This is a chemical reaction with an intermediate step.
What are the relationship between the product of the first step and the reactants of the second step?
The major product of the first step becomes the main reactant of the second step.
What is NaOH?
Sodium hydroxide
What is NH3?
Ammonia
What is the most significant property that NaOH and NH3 share?
They are both bases.
What elements are found in the first chemical structure?
Carbon, hydrogen, oxygen, sulfur, nitrogen, chlorine
What is removed from the reactants in the first step when the reactants combine?
Hydrogen is removed from one and chlorine is removed from another.
What other chemical(s) are formed in the first step that are not shown?
NaCl and H2O
The H and the Cl that were removed will combine with NaOH to make NaCl and H2O
What is the chemical formula of the second reactant in the first step?
C5NO2H9
What happens in the second step of the reaction?
The functional group attached to the sulfur is removed. (This is called an acetyl group.)
What does the other product of the second step look like?
This is a ball-and-stick model of acetamide, with carbon in black, nitrogen in blue, oxygen in red, and hydrogen in white. You would not be expected to know the name of this. But you could deduce the structure by realizing that the acetyl group (on the left) combines with NH3 (on the right).
Goals of this image:
- Interpret organic molecular diagrams
- Carbons are represented by ends of line segments
- Hydrogens are implied wherever a carbon is not shown with 4 bonds
- Interpret multiple step chemical reactions
- Recognize that the product of the first step becomes the reactant for the second step
- Recognize that not all chemicals involved in the reaction are shown
- Recognize important simple molecules
- NaOH
- NH3
