Tags and Description

33 Terms

1

Organic compounds

compounds containing carbon, which is the building blocks of life.

New cards
2

characteristics of Organic Compounds

  • Non-polar

  • Insoluble in water

  • Covalently bonded

  • Don’t conduct electricity

  • Lower melting and boiling points

  • Very flammable

  • react slowly

New cards
3

Hydrocarbons

Compounds containing just Hydrogen and Carbon

New cards
4

Alkanes

Hydrocarbons which are saturated, and contain only single bonds between the carbons. General Formula: CₙH₂ₙ₊₂.

New cards
5

Alkenes

hydrocarbons which are unsaturated, and contain a double bond between two of the Carbons. General Formula: CₙH₂ₙ

New cards
6

Alkynes

hydrocarbons which are unsaturated, and contain a double bond between two of the Carbons. General Formula: CₙH₂ₙ-₂

New cards
7

Saturated hydrocarbons

hydrocarbons which can’t hold anymore atoms, like alkanes.

New cards
8

Unsaturated hydrocarbons

Hydrocarbons which could hold more atoms, by breaking multiple bond, like alkenes, and alkynes.

New cards
9

Methyl group

An extra CH₃ attached to one of the carbons

New cards
10

Ethyl Group

An extra C₂H₅ attached to one of the Carbons

New cards
11

Propyl Group

An extra C₃H₇ attached to one of the carbons.

New cards
12

Isomers

Molecules with the same molecular formula, but different structres.

New cards
13

Functional Groups

Types of Organic compounds which have specific parts which allow them to perform certainactions.

New cards
14

R in General Formulas

represents a chain of Hydrocarbons

New cards
15

halocarbon

Functional Group with a Hydrocarbon bonded to halogens (Group 17 elements). Name ending is the same as the hydorcarbon.

New cards
16

Alcohol

Functional Group with a Hydrocarbon bonded to a hydroxide ion. (R-OH), the name ends with “-anol”

New cards
17

Ether

Functional Group with two hydrocarbon groups on either side of an oxygen (R-O-R’). Name ends with “ether"

New cards
18

Aldehyde

Functional Group with a hydrocarbon bonded to a C, which is double bonded to an O, and single bonded to an H. ends with “-anal”

New cards
19

Ketone

Functional Group with 2 Hydrocarbon chains on either side of a C which is double bonded to an Oxygen. ends with “-anone”

New cards
20

Organic Acid

Functional Group with a hydrocarbon bnded to a C, which is single bonded to an OH, and double bonded to another O. ends with “-anoic acid”.

New cards
21

Ester

Functional Group with two Hydrocarbon chains one either side of a C-O, and that C is double bonded to an O. end with “-anoate”

New cards
22

Amine

Functional Group with Hydrocarbons bonded to Nitrogen. ends with “-amine”

New cards
23

Amide

Functional Group with 2 Hydrocarbons, one bonded to a C, which is also double binded to an O, and single bonded to an NH, which is then bonded to the other chain. ends with “-amide”

New cards
24

Combustion Reaction

Hydrocarbon + O₂ →H₂O + CO₂

New cards
25

Substitution Reaction

Another element like a Halogen is added to a saturated hydrocarbon (alkane), and it replaces one of the Hydrogens, releasing it from the molecule.

New cards
26

Additional Reaction

Another element is added to an unsaturated hydrocarbon (alkene, or alkyne), where it breaks one of the multiple bonds, and the product is just one compound.

New cards
27

Esterification Reaction

Organic Acid + Alcohol → Ester + H₂O. Makes Ester

New cards
28

Saponification

Ester + A base → An acid(ion) + Alcohol. How soap is made.

New cards
29

Fermentation Reaction

A Carbohydrate (ex: sugar) → Alcohol + CO₂. How yeast works, and alcoholic beverages are made.

New cards
30

Polymerization reaction

Taking multiple smaller molecules (Monomers), and attaching them together to form a larger polymer.

New cards
31

Addition polymers

breaking the emulripple bonds in monomers to attach them together, to form the polymer.

New cards
32

Condensation polymers

Taking water away from the monomers so they can bond and form a polymer.

New cards
33

Cracking

Using heat to break down bigger complex hydrocarbons, into smaller and more useful hydrocarbons.
