[16.2] synthetic routes Flashcards
1
Q
what does HBr commonly react with?
A
- alcohol (substitution)
- alkene (addition)
2
Q
what does acidified dichromate commonly react with?
A
- alcohol (oxidation, but not tertiary)
- aldehyde (oxidation)
3
Q
what does Br₂ commonly react with?
A
- alkane (substitution)
- alkene (addition)
4
Q
what is a target molecule?
A
it is the compound that the chemist is attempting to prepare by organic synthesis
5
Q
how can the target molecule be obtained in simple synthesis?
A
in simple synthesis, the target molecule can be obtained by reacting a readily available starting material with a readily available reagent in a one-step reaction
6
Q
what other steps may be needed if synthesis is not straightforward?
A
some organic syntheses require many steps to change functional groups or to add carbon atoms to the chain length to obtain the target molecule
7
Q
what do you need to do for two stage synthesis?
A
- identify the functional groups in your starting and target molecules
- identify the intermediate that links the starting and target molecules
- state the reagents and conditions for each step
