Lesson 3 Alkene And Alkyne Flashcards
Possesses one or more carbon double bonds
Alkenes
Formula of alkene
CnH2n
What is the simpliest alkene
Ethene
Properties of Alkene
- Properties similar to alkanes
- Boiling point increases with molar mass
- Insoluble in Water but Soluble in Organico compounds
What is alkene used for?
Production of plastic and rubber
Contains one or more carbon-carbon triple bonds
Alkyne
Formula of Alkyne
C n H 2n–2
Simplest
Colorless
Flammable
Ethyne
Colorless
PUNGENT ODOR
Production of chemicals
Propyne
Garlic like odor
Colorless
Used for fuel and starting material
Butyne
4 major types of Alkene Reaction
- Addition reaction
- Elimination reaction
- Rearrangement reaction
- Substitution reaction
4 major types of Alkene Reaction
- Addition reaction
- Elimination reaction
- Rearrangement reaction
- Substitution reaction
What reaction converts AlkEne to AlkAnes by adding molecules
Addition reaction
3 types of Addition Reaction
With hydrogen, water and halogen
Predicts the major product in reactions with HX
Markovnikov’s Rule (under addition reaction)
What reaction is when two groups are Removed from a molecule
Elimination reaction
What reaction is when molecules undergoes Structural Change
Rearrangement reaction
What reaction is when one atom is Replaced by another atom
Substitution reaction
What is the classification of AlkEne
- Family of hydrocarbons
- Contains one carbon-carbon double bond
The most important COMMERCIAL reaction of Alkene. In which small molecules are arranged into giant molecules.
Alkene Polymers
Two types of polymerization
Addition and condensation polymerization
Reacts in complex molecules that can result in multiple possible products
Hydrohalogenation snd hydration
Reacts in complex molecules that can result in multiple possible products
Hydrohalogenation snd hydration
Used in listing down alkenes systematically
iupac Nomenclature
These are produced in factories can be melted, formed into a giant bubble and then made into a film
Polyethene pellets
