some species below react with fe2+ and some do not. for each that does write the equation with products for those that don't write no reaction -na (s) -na+ (aq) -co (s) -co2+ (aq) -h+ (aq)
Calculate the final temperature when a 25.6 gram sample of ice at 0oC is placed into a styrofoam cup containing 115 grams of water at 75.0 oC. Assume that there is no loss or gain of heat from the surroundings.
Microorganisms reduce carbonyl compounds to alochols stereoselectively. 5-chloro-2-pentanone is reduced to (S)-5-chloro-2-pentanol in this way. Distillation of this alcohol over sodium hydride gives a chiral cyclic ether.
Draw both products of bromination of cholesterol which you obtained. What is the stereochemical relationship between them
