how many +I groups ketone
2
1 of 17
how many +I groups aldehyde
1
2 of 17
which are more reactive aldehydes or ketones
aldehydes - as ketones have more +I groups/aklyl groups which are e releasing and therefore stabilizing
3 of 17
reduction of aldehydes /ketones requires
reducing agents NaBH4 or LiAlH4
4 of 17
what do these reducing agents provide
the H:- nucleophile
5 of 17
what type of compound are NaBH4 and LiAlH4
ionic compounds
6 of 17
Gringnard reaction
involves organometalics - this is the only time C has delta - charge (when attached to metal)
7 of 17
Grignard reaction - describe mechanism
pair of 2 from c. bond between c-M donates e to electrophile. Metal detaches. result - R-EL + M+
8 of 17
in Gringard aldehydes are converted to
secondary alcohols
9 of 17
in the gringard reaction ketones are converted to
tertiary alcohols
10 of 17
what does the reaction require
a drying agent - ie CaCl2
11 of 17
how can we produce acyl chlorides
COOH + thionyl chloride
12 of 17
chymotrypsin
digestive enzyme - catalyses the hydrolysis of amide linkages between AAs
13 of 17
Rhodopsin is a
imine
14 of 17
what does light do to rhodopsin
activates it flipping from Z--> E
15 of 17
Hydride transfer in nature
during photosynthesis and respiration transfer from NADP--> NADPH
16 of 17
if NADP/NAD is present
these are reducing agents - themselves oxidised
