Daily Reflection Prompt: Write 3 facts about polymers.
What is a Isomer? Compounds that have the same chemical formula but different structural formulas are called isomers Butanes and isobutane have different melting points and boiling points
Double Bond Single bond hydrocarbons end in “-ane” like Propane Double Bond hydrocarbons end in “-ene” or “-yne” like Ethene.
Hydroxyl Group Hydroxyl group is a “OH” compound used for substitute for hydrogen atom in hydrocarbons Alcohol is a substituted hydrocarbon that contains one or more hydroxyl group Ethanol is produced natually by yeast when they consure sugar stored in corn, wheat and barley Methanol (poisonous) Ethanol
Polymers vs. Monomers Polymer: A very large molecule (millions of atoms) made of a chain of many smaller molecules. Monomer: Smaller molecule – the links that make up the chain
What do plastics and cells in your body have in common? They are both made of carbon compounds
What are the four types of polymers found in all living things? Carbohydrates Lipids Proteins Nucleic Acids ????????
Carbons can form four covalent bonds They can also bond to each other in changes and ring shaped groups
What are composites Composites combine two or more substances as a new material with different properties
What is the simplest carbohydrates? Sugar One of the most important sugars in your body is glucose C 6 H 12 O 6 Glucose is also known as “blood sugar” because it is circulated through out your body
