6 Which of the Following Is the Strongest Acid

NH4 Ka 56 101. Wed Apr 29 2009 the strongest acid by a long way is the hydrochloric acid - it is almost completely dissociated in water.

Pin On Organic Chemistry

The toughness of the acid is identified by the main atoms electronegativity relative.

. COOH COOH COOH a COOH COOH COOH B II C III D IV E V. HAaq H2Ol H3Oaq Aaq note that H3O and H. F is the most.

R stands for Resonance. Nitric Acid HNO3 6. Hydrochloric Acid HCl 2.

This is the general order in which I want you to think of in terms of looking at the acidity of a compound. The correct option is C CHCN3. Oxy acids of chlorine and their number of pπ-dπ bonds given as.

Driving Tests India Mass Communication and Journalism. Based on the given examples Ka is the highest for Acid B 25 10⁶. Which is the following is the strongest acid.

The compound E is the strongest acid. This is because the conjugate base ClO 4 ion is the weakest base. CCl_3COOH CHCl_2COOH CH_2ClCOOH CH_3COOH.

The seven most common strong acids are hydrochloric acid nitric acid sulfuric acid hydrobromic acid hydroiodic acid perchloric acid and chloric acid. Strength of Conjugate base order. FCH2COOH is the strongest acid out of all.

Among oxyacids of halogens the decreasing order of the acid strength is. HOCl Ka 40 108. So the answer is CHCN3.

NTSE Previous Papers Online. A is more important generally than R R is more important generally than I and O is normally the last on the list. HClO 4 HClO 3 HClO 2 HClO Hence option C is correct.

Bihar Police Exam Tests. So the strongest acid is CCl_3COOH. FCH2COOH ClCH2COOH BrCH2COOH ICH2COOH.

Hence the delocalisation of negative charge gives rise to the most stable conjugate base. 6 required strong acids. Among the given acids perchloric acid HClO 4 is the strongest acid.

Since the inductive effect from the closest ortho-position is the strongest one excepts o-nitrophenol to be a stronger acid than p-nitrophenol. COOH COOH COOH a COOH COOH COOH B II C III D IV E V. Hydroiodic Acid HI 4.

Correct option is B First of all anything with a positive charge is a stronger acid because its conju view the full answer. Since chlorine is an electron withdrawing group having negative inductive effect the acidity of the compound increases when attached to a more withdrawing group. Beckers standard chem class.

Recall that smaller values that pKa exchange mail to greater acid strength. Thus the order of acidity is. As we know the greater the number of electron withdrawing groups halogens stronger will be the acid.

Chloric acid hydrobromic acid hydrochloric acid hydroiodic acid nitric acid perchloric acid and sulfuric acid. A stands for Atom. Hence Acid B is the strongest acid.

6 of the strongest acids and 6 of the strongest bases Learn with flashcards games and more for free. Acidic strength increases as the stability of the conjugate base increases. Most other acids people encounter are weak acids.

There are 7 strong acids. Postal Exams Model Papers. List of Strong Acids 1.

Therefore the correct option is D. Since the electron withdrawing inductive effect -I effect of the halogens decreases in the order of FCl Br I therefore the acidic strength of the α- halo acids decreases in the same order. The highest H comes from the acid HA that dissociates into H and A its conjugate base the most.

The benzoic acid is a meta directing group and chlorine as substituents at C-2 C-3 C-4 C-5 and C-6 make the compound the strongest acid. HCN Ka 62 1010. CH3CO2H Ka 18 105.

Strong acid means weak conjugate base. C C l 3 C O O C H C l 2 C O O C H 2 C l C O O C H 3 C O O So strongest acid is C C l 3 C O O. Mar 4 2017 HCl is the only strong acid in this selection of acids.

However the intramolecular hydrogen bond in o-nitrophenol must be broken to release proton and this requires some energy. Being part of the list of strong acids doesnt give any indication of how dangerous or damaging an acid is though. Dont get confused between the I effect and I effect.

HOCl pKa 75 a 86 a 106. In case of ClO-there is no π-bond hence if form less stable conjugate base hence act as weak acid while in case of ClO 4-it has three pπ-dπ bond which stablised greater extent and form more stable conjugate base hence it conjugate acid HClO 4 is strongest acid. Terms in this set 6 H2SO4.

NIFT UG PG Previous Papers Online. These are related to the letters A R I and O. Here the cyano group makes the conjugate base formed carbanion stable owing to its electron withdrawing tendency.

Which of the following is the strongest acid. HA H A-Ka HA-HA Now higher the Ka value greater is the dissociation and stronger is the acid strength. AP Police and SI Exam Tests.

Thus the decreasing order is. In the case of halides C H F 3 may seem to be the strongest acid but it is not. Sulphuric Acid H2SO4 5.

Therefore HOCl is the the strongest acid and HOI is weakest and also acid stamin decreases as the central halogen descends on the periodic table. Phosphoric acid on the other hand gives up one proton very reluctantly - only about 1 in 10 000. Hydrobromic Acid HBr 3.

Under most definitions the acid dissociates into a positively-charged hydrogen ion proton and a negatively-charged anion. Video Explanation Was this answer helpful. 6 Which of the following is the strongest acid.

6 Which of the following is the strongest acid. HCO2H Ka 18 104. For a hypothetical monoprotic acid HA the dissociation equilibrium is.

Therefore D C H C N 3 is the strongest acid. NCHMCT JEE Previous Papers Online.
