Increases
Propofol is in what functional group?
Alcohols
Sevoflurane is in what functional group?
Halogenated ethers
Ketamine is in what functional group?
Amines
Epi is in what functional group?
Amines
Tetracaine is in what functional group?
Esters
Chloroprocaine is in what functional group?
Esters
Dopamine is in what functional group?
Amines
Cocaine is in what functional group?
Esters
Lidocaine is in what functional group?
Amides
Bupivicaine is in what functional group?
Amides
Molecular compounds are comprised of only ____
Nonmetals
Do not use nitrous oxide if patient has a suspected _____
Pneumothorax
The hydrogenation of ______ can be used to convert liquid vegetable oils into solid shortening (crisco)
Alkenes
______ are one of the main components used to create polymers (plastics)
Alkenes
Why halogenated ethers vs original ethers?
Halogenation partially oxidizes the molecule making it less flammable than normal ethers. Halogenated ethers are also more bioavailable.
