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 17 of 17
