Organic Chemistry Flashcards
What is Organic Chemistry
Chemistry involving hydrocarbons; or molecules w/ mostly C and H atoms
Ways to draw organic compounds
Formula (C6H14)
Lewis structure (H3C-CH2-CH2-CH2-CH2-CH3
Skeletal structure using lines for bonds and vertexes/points for carbons
What are Isomers
Organic compounds with the same formula but different arrangement of atoms
What are the different types of isomers
Structural, positional, functional group, chain and stereoisomers
Stereo isomers
Molecules which have the same atoms connected to each other but different arrangements in space (Are 3D)
Geometric isomers
Isomers w/ double or triple bonds which differ in the arrangements in space and can’t be moved much like singe bonds can
Cis
A compound with functional groups of chains on the same side
Trans
A compound with functional groups of chains on opposite sides
Structural isomer
Changes the structure of the compound
Positional isomer
Changes functional group position
(From 1,2 to 1,3 Dibromopropane)
Functional group isomer
Changes type of functional group(s)
(Same elements, diff functional groups)
Optical isomers
A carbon with 4 functional groups that can form an isomer where the images cannot overlay
What is Infrared Spectroscopy
An interaction between matter and light (Electromagnetic radiation) that shows what type of functional groups a compound has
What trends show up on an infrared spectrum for different functional groups
C-H bond: 2850-3100; deep straight dip
O-H bond: 2500-3650 ; deep, wide, and curved dip
C=O bond: 1640-1759
C and triple bonded N: 2200-2250
Carbon ring: less than 1200; many narrow and deep dips
What is the substitition reaction of alkanes
Free radical substitution
Steps to a free radical substitution
Step 0, Initiation step, Propagation step, and Termination step
What are free radical(s)
Atoms or molecules with an unpaired electron
What is a saturated hydrocarbon?
A hydrocarbon w/ only single bonds
(C — C)
What are unsaturated hydrocarbons?
Hydrocarbons with two double bonded carbons (C=C)
What is an empirical formula? At
Shows the simplest whole number ratio of atoms of each element in the compound (Ex. H2O, HO2CCO2H, CaC2O4)
KMnO4 is…
Potassium Maganate (Adds oxygen/ oxidizes a compound)
Energy change formula = ?
mc delta T
How are orbitals in an atom organized?
Different layers around the nucleus called electron shells, each growing bigger in size and energy the farther away from the nucleus
Shell levels are organized how?
1st shell - Contain 2 electrons and only 1s
2nd shell - Contain 8 electrons, has one 2s orbital and a three 2p orbitals
3rd shell - Contains 8 but can also hold up to 18, has a 3s, three 3p orbitals, and five 3D orbitals
