Types of Organic Reactions + Reaction Mechanisms : Bond Breaking and Bond Formation (Part 1) Flashcards
what is a substitution ?
is a reaction in which an atom or a group of atoms is replaced by another atom or group of atoms.
Which bonds are involved in susbtitution ?
sigma ()bonds: one bond breaks and another one forms at the same carbon atom.
what is the most coomon substitution ?
when Z is a hydrogen or a heteroatom that is more electronegative than carbon.
Common examples of substitution
substitution are reactions involving alcohols or haloalkanes
Common examples of substitution
substitution are reactions involving alcohols or haloalkanes
what is an addition reaction ?
a reaction in which two molecules add together to form a single product
what are addition reaction a characteristic of ?
unsaturated compounds with multiple bonds such as alkenes, alkynes and carbonyl compounds
what are elimination reactions ?
involves a reaction in which a simple molecule splits off from within a larger molecule to form a double bond.
what are elimination reactions ?
involves a reaction in which a simple molecule splits off from within a larger molecule to form a double bond.
most common examples of elimination
when X = H and Y is a heteroatom more electronegative than carbon.
most common examples of elimination
when X = H and Y is a heteroatom more electronegative than carbon.
what is the force for an elimination reaction ?
the formation of a small, stable molecule
what is a reaction mechanism ?
a detailed description of how bonds are broken and formed as starting material is converted into product.

what are the 2 reactive intermidiates ?
ions or radicals
