2,4,6-Trinitrophenol is highly acidic in nature as three electron withdrawing groups (Nitro group) are attached to it. These electron withdrawing groups on phenol make it highly acidic. That’s why it is known as picric acid.
What is the use of picric acid?
Picric acid is used in the production of explosives, matches, and electric batteries. It is also used in etching copper and manufacturing colored glass, in the leather industry, and in the synthesis of dyes. Picric acid is very unstable and is a flammmable/combustible material.
Which compound is most acidic?
Hence, picric acid, also known as – 2,4,6,-trinitrophenol – will be the strongest acid!
What is the full form of TNT?
trinitrotoluene (TNT), a pale yellow, solid organic nitrogen compound used chiefly as an explosive, prepared by stepwise nitration of toluene.
How do you make TNT in a lab?
First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mononitrotoluene (MNT). The MNT is separated and then renitrated to dinitrotoluene (DNT). In the final step, the DNT is nitrated to trinitrotoluene (TNT) using an anhydrous mixture of nitric acid and oleum.
Which of the following is most acidic?
Q. Which of the following is most acidic?
- Benzyl alcohol. 26%
- Cyclohexanol. 12%
- Phenol. 10%
- m-Chlorophenol. 52%
Which acid is used for producing explosives?
Nitric acid is also used in the manufacture of explosives, such as nitrobenzene derivatives, dinitrotoluene derivative, and TNT derivatives, and for producing other chemical intermediates.
Is carbonic acid acidic?
In aqueous solution carbonic acid behaves as a dibasic acid. The Bjerrum plot shows typical equilibrium concentrations, in solution, in seawater, of carbon dioxide and the various species derived from it, as a function of pH.
Which one is more acidic and why?
Positively charged molecules, or ions, are more acidic than neutral ones. … The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. Look at the strengths in the bonds between the molecules in the ion. The more lopsided it is throughout the molecule, the stronger the acid.
Why is phenol acidic than alcohol?
Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom, as it is in an alkoxide ion, but is delocalized-it is shared by a number of carbon atoms in the benzene ring.
Which is more acidic phenol or acetic acid?
Acetic acid (ethanoic acid, pKa≈5) is more acidic than phenol (pKa≈10), which is reflected in their reactivity with a weak base such as sodium carbonate (adding acetic acid leads to effervescence of carbon dioxide).
Which is more acidic picric acid or carbonic acid?
The presence of three nitro groups at ortho-para positions increases the acidity of the compound. … EWG ( electron withdrawing group ) increases the acidic character of any compound. And hence picric acid becomes a stronger acid than phenol and carbonic acid.
Which is more acidic phenol or picric acid?
Three —NO2 groups in picric acid deactivate the phenolate ion. Due to electron withdrawing nature of —NO2 groups, picric acid becomes stronger acid than phenol.
Which acid is strongest or which is most acidic?
Acid Strength and Bond Strength
The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5). Hydrochloric acid: Hydrochloric acid is a clear, colorless solution of hydrogen chloride (HCl) in water.
Which of the following is weakest acid?
Proton doners are acids. Electron withdrawing groups (like halogens) increase the acidity of carboxylic acids. Therefore, HCOOH is weakest acid among the given choices.
How do you know what’s the most acidic?
Water molecule is one of the most stable substances known. How do we know which proton is the most acidic in a molecule (such as acetic acid) that contains more than one type of proton? Remember that the higher the degree of positive character on the proton, the more acidic it is.
What is C4 made of?
C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source.
Who invented dynamite?
Swedish chemist, inventor, engineer, entrepreneur and business man Alfred Nobel had acquired 355 patents worldwide when he died in 1896. He invented dynamite and experimented in making synthetic rubber, leather and artificial silk among many other things.
Can dynamite explode without a blasting cap?
Crystals will form on the outside of the sticks, causing them to be even more sensitive to shock, friction, and temperature. Therefore, while the risk of an explosion without the use of a blasting cap is minimal for fresh dynamite, old dynamite is dangerous.
What is the full form of the PDF?
PDF stands for “portable document format“. Essentially, the format is used when you need to save files that cannot be modified but still need to be easily shared and printed. Today almost everyone has a version of Adobe Reader or other program on their computer that can read a PDF file.
What is LAN An abbreviation of?
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
