Is MeLi a strong base?
Reactivity. Methyllithium is both strongly basic and highly nucleophilic due to the partial negative charge on carbon and is therefore particularly reactive towards electron acceptors and proton donors. Nonmetal halides are converted to methyl compounds with methyllithium: PCl3 + 3 MeLi → PMe3 + 3 LiCl.
What is the pKa of hydrogen?
pKa Values for Organic and Inorganic Bronsted Acids at 25 oC
Is lower pKa favored?
Lower pKA value corresponds to stronger acid of the conjugate acid, and thus weaker conjugate base. The base with a stronger conjugate acid (lower pKa value) will be the weaker base and will be favored at equilibrium.
What is the pKa of COOH?
Values of pKa for common alkyl carboxylic acids are around 5 (Ka ~ 10-5).
What are the values of PKA in organic chemistry?
Carboxylic acids 4, 8 Pyrazine 26 Aliphatic 4, 8 Aromatic 7, 8 Quinoline 27 Phenols 9 Quinazoline 27 Alcohols and oxygen acids 10, 11 Quinoxaline 27 Amino Acids 12 Special Nitrogen Compounds 28 Peptides 13 Hydroxylamines 28 Nitrogen Compounds 14 Hydrazines 28 Aliphatic amines 15, 17, 19 Semicarbazones 28 Cyanoamines 16 Amidoximes 28
What is the pKa value of phenazine?
pKa Data Compiled by R. Williams pKa Values INDEX Inorganic 2 Phenazine 24 Phosphates 3 Pyridine 25 Carboxylic acids 4, 8 Pyrazine 26 Aliphatic 4, 8
Which is more Insoluble magnesium carbonate or MgO?
Practically insoluble both in water or ethanol White, friable masses or bulky, white powder; at about 700 °C is converted to MgO; sol in about 3,300 parts CO2-free water; more sol in water containing CO2; sol in dilute acids with effervescence; insol in alcohol /Magnesium carbonate hydroxide/ Budavari, S. (ed.).
What is the purpose of magnesium oxide ( MgO )?
Magnesium oxide (MgO). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses. InChI=1S/Mg.O 13589-16-7, 185461-91-0, 187036-80-2, 52933-73-0, 82375-77-7, 227961-49-1, 1193320-89-6
