protonate

The candle dissolved, showing the ability of the acid to protonate hydrocarbons.

Very strong acids such as hydrochloric acid are required to protonate indole.

(Under normal acidic conditions hydrocarbons do not protonate very much.)

Strong acids protonate the oxygen to give "onium ions."

In addition, the general acidic ligand required to protonate the urea nitrogen was not identified.

However, a Lewis base can be very difficult to protonate, yet still react with a Lewis acid.

Trifluoroacetic acid does not protonate the molecule.

Superacids can permanently protonate water to give ionic, crystalline hydronium "salts".

The orange solution is then treated with sulfuric acid to protonate the anionic intermediate, giving the neutral product.

The protons can then serve two functions, namely to protonate basic groups of the collagen and neutralize solution alkali chemicals.

The 1:1 combination forms the strongest known superacid, which has been demonstrated to protonate even hydrocarbons to afford carbocations and H.

The acetic acid formed will then protonate the DMAP.

HHe cannot be prepared in a condensed phase, as it would protonate any anion, molecule or atom with which it were associated.

The enzyme then acts as a general acid to protonate the β-carbon, resulting in the formation of (S)-methylmalonyl-CoA.

The acetic acid will protonate the carbonate, making carbonic acid, which forms water and carbon dioxide, which bubbles away.

H(CHBCl) is the only acid known to protonate C fullerene without decomposing it.

Dilute hydrochloric acid is added to the reaction mixture to protonate the benzoate salts, as well as to dissolve the magnesium salts.

Disulfuric acid is strong enough to protonate "normal" sulfuric acid in the (anhydrous) sulfuric acid solvent system.

By contrast, the univalent anions perchlorate and permanganate ions are very difficult to protonate and so the corresponding acids are strong acids.

For example, an amine like strychnine can react with hydrochloric acid to protonate a nitrogen atom in the strychnine, making a positively-charged conjugate acid.

There are two histidine residues located at the active site which are thought to protonate the reduced flavin molecule and the leaving phosphate group of the substrate.

As a bicyclic, heterocyclic purine derivative, uric acid does not protonate at an oxygen [-OH] like carboxylic acids do.

Strong acids protonate the carbonyl, which makes the oxygen positively charged, so that it can easily receive the double bond electrons when the alcohol attacks the carbonyl carbon.

Replies: Kimmie, The acid can protonate the carboxyl group of the methyl benzoate thereby producing an ionic species which is soluble in the polar sulfuric acid.

A simple definition of aliphatic amines that are likely to protonate at physiological pH can be written as the following recursive SMARTS:
