Organic Chemistry Flashcards
Homologous series
families of organic compounds with the same functional group and same general formula.
Order of priority
Carboxylic acids>aldehydes>ketones>alcohols>alkenes>halogenoalkanes
Catalytic cracking
The breaking down of alkanes or larger molecules in order to produce smaller molecules to be used in different industries
Free radical
an atom or group of atoms with an unpaired electron
Nucleophile
A nucleophile is a species attracted to a region of positive charge and is an electron pair donor.
Electrophile
An electrophile is a species attracted to a region of negative charge and is an electron pair acceptor
Electrophilic addition
A type of reaction where an electrophilic species combines with another compound to form a product without losing any atoms present in the reactants.
Free radical substitution
A type of reaction when hydrogen atoms on an alkane are substituted by a halogen atom
Nucleophilic substitution
A type of reaction when a nucleophile replaces a halogen atom
Primary
When a halogen or a foreign molecule is bonded to a carbon with 2 hydrogen atoms
Secondary
When a halogen or a foreign molecule is bonded to a carbon with 1 hydrogen atom
Tertiary
When a halogen or a foreign molecule is bonded to a cation with no hydrogen bonded to it
Sigma bonds (Two eyes overlapping)
A type of covalent bond result from end to end overlapping of atomic orbitals. The electron density in a σ bond is symmetrical about a line joining the nuclei of the atoms forming the bond. The pair of electrons is found between the nuclei of the two atoms. The electrostatic attraction between the electrons and nuclei bonds the atoms to each other
Pi bonds (Dumbbell)
A type of covalent bond resulting from the sideways overlap of adjacent p orbitals. The two lobes that make up the π bond lie above and below the plane of the σ bond. This maximizes overlap of the p orbitals. A single π bond is drawn as two electron clouds, one arising from each lobe of the p orbitals. The two clouds of electrons in a π bond represent one bond containing two electrons
