To make a Wittig reagent, one can react an aldehyde or ketone with a phosphonium ylide. This reaction forms a carbon-carbon double bond, which is the key feature of a Wittig reagent. The resulting compound can be used in organic synthesis to convert carbonyl compounds into alkenes.
Use a graduated pipette or syringe to measure and transfer 5ml of liquid reagent from the large reagent bottle. Make sure to carefully handle and dispense the reagent to avoid spills and contamination.
Aldehydes and ketones add only one equivalent of Grignard reagent because the reaction forms a stable intermediate that prevents further addition of the reagent.
the amount of limiting reagent
No, the excess reagent does not determine the amount of product formed in a chemical reaction. The amount of product is determined by the limiting reagent, which is the reactant that is completely consumed first. The excess reagent will remain in excess after the reaction is complete.
The one that runs out first in a reaction - is thoroughly accurate. There are quite a few other limiting reagents in limiting reactions - as well.
i dont quite understand what your saying but if you mean using reagents to make a reagent like transmute bone. when you make the bone or whatever you will get rid of about 2 reagents to make one hard to find reagent to me not worth it. -Zarchary DayGlen on wizard101
