you react the grignard with either an ester, an acid chloride or a ketone to get a tertiary alchohol. if you react a grignard reagent with an aldehyde you get a secondary alcohol and if you react the grignard with formaldehyde (methenal) you get a primary alchohol. same thing happens if u use R-Li instead of a grignard reagant.
What else can I help you with?
What is the best way to obtain 5ml of liquid reagent from a large reagent bottle?
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.
How can one make a Wittig reagent?
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.
Does the excess reagent determine the amount of a product?
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.
Why grignard reagent cannot be prepared by calcium instead of magnisium?
The beauty of grignard reagents is their relative ease of production, in simple terms just take an alkyl halide add magnesium and stir to get RMgX which can then be reacted further.The difficulty in using calcium is that the metal itself is less reactive and calcium organometallics are relativelly unstable. Calcium organohalides are also more salt-like and are not as soluble as their Mg counterpart.This whole area is not that well understood, the mechanism of production of grignards is unclear. Certainly alkylcalcium halides are known but they are difficult to prepare and are described as extremely unrreactive.If you have access to a library then see:-Volume 252, Issues 15-17, August 2008, Pages 1516-1531Recent Advances in Organometallic Chemistry: 2008ReviewHeavy Grignard reagents-Synthesis and reactivity of organocalcium compounds by Matthias Westerhausen
What tertiary colors make the color plum?
Plum is a tertiary color formed by mixing equal parts of purple and red-orange.
Why grignard reagent always kept in dry ether?
During the formation of Grignard's reagent dry or anhydrous ether is used to prevent the magnesium from moisture because in presence of water magnesium leaves the organic material and combines with water.
Why Tetra hydro fluorine is used in Grignard reagents?
It isn't, and as far as I am aware, tetra hydro fluorine does not exist. THF stands for tetra-hydro-furan, a very effective heterocycle solvent. For structure, think a cyclo-pentane where a CH2 has been swapped for an oxygen atom. It is used because it is a very polar ether, and so able to solvate organometallic compounds like grignard reagents, but, unlike other polar solvents, like water, alcohols, and ketones, it will not react with the (expensive) organometallic reagent.
What is the equation for the preparation of ketones from secondary alcohols?
You can only make any ketone from any secondary alcohol by using PCC, Jones reagent, or NaCr2O4 in acid as a reagent.
What will you do if you transfer a reagent to another reagent?
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
How do you detect benzene in the Grignard synthesis of benzoic acid?
Not sure what you mean... If you mean 'how is benzene used for the Grignard synthesis of Benzoic Acid,' then the answer is, bromobenzene (C6H5Br) is turned into phenyl Grignard (C6H5MgBr) by the addition of Magnesium in ether, and then dry ice (solid CO2) is added to the reaction mixture to make Benzoate (C6H5COO-), which is the conjugate base of Benzoic Acid. That has got to help you somehow.

Entertainment and Tourism are the key areas that make the Tertiary sector

How do you make FRAP reagent?
To make FRAP (Ferric Reducing Antioxidant Power) reagent, mix 25 ml of acetate buffer, 2.5 ml of TPTZ solution, and 2.5 ml of FeCl3 solution. Store the reagent in a dark container at 4°C until needed.
