Which one of the following compound is least acidic?

$o – cresol$ is least acidic and it is the correct option from the above information.

Which is the most acidic one?

Hence, picric acid, also known as – 2,4,6,-trinitrophenol – will be the strongest acid!

Which of the following is least acidic nature?

Q. Among the following, which is least acidic?

• phenol. 21\%
• o-cresol. 60\%
• p-nitrophenol. 12\%
• p-chlorophenol. 8\%

Which of the following compounds is least acidic A Ethanol B P-nitrophenol C phenol d/m nitrophenol?

i. Although o-nitrophenol should be more acidic than p-nitrophenol, but due to intramolecular H-bonding it is less acidic.

Which acid is least acidic?

HF
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 pKa of about -9, is one the strongest acids known.

Which phenol is least acidic?

Phenoxide is stabilised by resonance effect only and it does not have any electron releasing group. So, it is more acidic than O-methyl phenol and O-methoxy phenol. But the absence of an electron-withdrawing group makes it less acidic than O-nitrophenol.

Which compound is acidic?

Examples of acids include the inorganic substances known as the mineral acids—sulfuric, nitric, hydrochloric, and phosphoric acids—and the organic compounds belonging to the carboxylic acid, sulfonic acid, and phenol groups.

How do you know which compound is the least acidic?

Find the size of the base of the atom as compared to the others. Larger atoms are closer to the bottom of the periodic table, while smaller ones are closer to the top. Compare the differences in molecular structure. The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is.

Which is less acidic phenol or p-nitrophenol?

In p-nitrophenol, after the releasing of H + ions, the negative charge on the phenoxide ion will be stabilized by strong –M effect of nitro group in the para position. Therefore, it is clear that phenol is less acidic than p-nitrophenol.

Which of these compound is least acidic a phenol B P cresol C ortho nitrophenol and para nitrophenol?

Electron donating group donate electrons to the phenol, as a result, the electron density of phenol increases. This strengthens the O—H bond and thus the release of proton become difficult which makes it less acidic. Hence the p-cresol (4-methylphenol) is less acidic than phenol and nitrophenol.

Which oxide is least acidic?

and hence, As4O6 in least acidic.
