The world's strongest superacid is fluoroantimonic acid, HSbF 6. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF 5 ). Various mixtures produce the superacid, but mixing equal ratios of the two acids produces the strongest superacid known to man. Properties of Fluoroantimonic Acid Superacid

HI, with a pK a of about -9, is one the strongest acids known. More importantly to the study of biological organic chemistry, this trend tells us that thiols are more acidic than alcohols.
Solved Which of the following compounds is most acidic? I
Acidic nature of organic compounds can be commented on the basis of stability of the resulting conjugate base . If the conjugate base thus formed is stable then the compound is more acidic or the hydrogen is more acidic and vice versa. For option A we can see there is only one acidic hydrogen ie the hydrogen connected to the oxygen atom.

For now, the concept is applied only to the influence of atomic radius on anion stability. Because fluoride is the least stable (most basic) of the halide conjugate bases, HF is the least acidic of the haloacids, only slightly stronger than acetic acid. HI, with a pK a of about -9, is one the strongest acids known.

Which one is the most acidic compound? A B C D Solution The correct option is C The hydrogen of phenol and substituted phenols are acidic in general. Acidity, is roughly a measure of the ease with which the compound (s) lose a proton. Hence, the compound which gives the most stable conjugate base will be the most acidic.

10 Common Acids and Chemical Structures
Which will be the most acidic hydrogen in both cases? Please explain. According to me, in the first compound 2 should be most acidic as in both 1 and 2, resonance occurs but 2's carbon is closer to the oxygen, which can stabilize the negative charge on carbon.

Carbonic acid is a chemical compound with the chemical formula H2CO3 H 2 CO 3 and is also a name sometimes given to solutions of carbon dioxide in water (carbonated water), because such solutions contain small amounts of H2CO3(aq) H 2 CO 3 ( aq). Carbonic acid, which is a weak acid, forms two kinds of salts: the carbonates and the bicarbonates.

Most of the acidic organic compounds are weak acids. Dissociation constant of acids (K a) value tells us about the acidity or strength of the acid. When Ka value is high, acidic strength is high. When we study about acidity of compounds, we have to look their reactions with following compounds and products and then observe reaction rates.

Example \(\PageIndex{1}\): Acidic Groups. Using the pK a table, estimate pK a values for the most acidic group on the compounds below, and draw the structure of the conjugate base that results when this group donates a proton. Use the pKa table above and/or from the Reference Tables.. Answer. a. The most acidic group is the protonated amine, pKa ~ 5-9
The most acidic compound among the following is
Positively charged molecules, or ions, are more acidic than neutral ones. Negatively charged ions tend to be basic. Examine the periodic table of elements to figure out the strength of the electronegativity. The further to the right on the periodic table the element bonded to the hydrogen is, the stronger the acid it makes.

The least acidic compound (second from the right) has no phenol group at all - aldehydes are not acidic. The most acidic compound (second from the left) is a phenol with an aldehyde in the 2 ( ortho ) position, and as a consequence the negative charge on the conjugate base can be delocalized to both oxygen atoms.

11.10: Identifying Acidic Protons. The most general principle ruling acid strength can be stated thus: strong acids have relatively stable conjugate bases. In general, the more stable the conjugate base, the stronger the acid. An important thing to remember is that stability and reactivity are inverse. The more stable a substance is, the less.

Perhaps the most famous superacid mixture is magic acid (which does sound like it's from a movie). Invented by the grandaddy of superacid chemistry, George Olah, this comprises a 1:1 mixture of fluorosulfuric acid and antimony pentafluoride.. This super acidic system is the strongest ever measured, with a Hammett acidity function of -28.
