Intro to Rcn Types & Mechanisms Flashcards
How many groups can rcns be divided into?
Four.
Rearrangement = scrambling of the structure occus. Through a biosynthetic pathway?
Substitution = where one group is replaced by another
Elimination = where two groups are lost to create a double bond
Addition = reverse of elimination.
two groups are added across a double bond.
What is reaction types?
What happens in a reaction.
What is mechanisms?
Illustrates how a reaction of organic compounds occurs.
Majority of mechanisms / reactions are of what type?
Ionic, which involve the motion of electron pairs.
Majority of mechanisms/reactions this year are ionic, with two important exceptions. What are they?
- Halogenation of alkanes
- Free radical addition to alkenes
What is the “normal” curly arrow representing a chemical reaction?
→
What is the curly arrow representing a reversible or equilibrium chemical reaction?
⇌
Reaction type: Rearrangement?
Scrambling of the structure occus. Through a biosynthetic pathway?
Reaction type: substition?
where one group is replaced by another
Reaction type: elimination?
where two groups are lost to create a double bond
Reaction type: addition?
reverse of elimination.
two groups are added across a double bond.
What is the curly arrow representing a motion of electron pair in ionic reactions?
It starts from a centre of high electron density, moving towards a centre of lower electron density?
double headed e- pair = ⤺
What is the curly arrow representing a motion of a single electron in radical reactions?
It starts from a centre of higher electron density, moving towards a centre of lower electron density?
single headed curly arrow (could only find straigth arrow for demo) carrying a single e-.
