- Find the value of Kb for the conjugate base of the following organic acids. (a) picric acid used in the manufacture of explosives; Ka = 0.16 (b) trichloroacetic acid used in the treatment of warts; Ka = 0.20arrow_forwardWill acetylene react with sodium hydride according to the following equation to form a salt and hydrogen, H2? Using pKa values given in Table 4.1, calculate Keq for this equilibrium.arrow_forwardFor each value of Ka, calculate the corresponding value of pKa. Which compound is the stronger acid? (a) Acetic add, Ka = 1.74 105 (b) Chloroacetic acid, Ka= 1.38 103arrow_forward
- What is the role of ammonium ion in the following reaction? NH3 H;0 H20 NHA + Select one: Conjugate acid Acid Conjugate base Basearrow_forward1/ Hydrolysis of CH;CH,NO, with 85% H,SO, gives? 2/ When benzyl alcohol is oxidised with KMNO4, the product obtained ? 3/ In the below sequence of reactions, A and B? NaCN (CH3),CO- (HCI) 4/ Which of the following is the strongest acid? CH;COOH , BRCH,COOH , CICH,COOH , FCH,COOH 5/ Which substituted benzoic acid is most acidic? .CO2H CH3 .co,H CO2H CI .CO2H CH, 6/ Which acid is strongest or Which is most acidic? а) Cl,CH.COOН b) CICH,COOН c) CH;COOH d) CI3C.COOH 71. In the anion HCOO- the two carbon-oxygen bonds are found to be of equal length. What is the reason for it?arrow_forwardNaHCO3 can deprotonate benzoic acid but cannot deprotonate phenol. On the other hand, NaOH can deprotonate both benzoic acid and phenol. Given this information, rank the molecules numbered I to V in order of decreasing acidity. COH cOH он H,0 H,CO, IV CH3 II I II (A) V > II >I > III > IV (В) II > 1 > V > III IV (C) II > V >I > IV > IIarrow_forward

Which of the following compounds has the lowest pKa ? A OH NH B XOH OH C X D NH₂arrow_forwardEquilibrium of methyl orangea) Give a balanced reaction equation for the reaction of methyl orange with 6M HCl b) Give a balanced reaction equation for the reaction of methyl orange with 6M NaOHc) Use Le Chatelier’s Principle to explain the color change when acid or base is added to methyl Orange. Reaction: HMO = H^+ +MO^-arrow_forward
- Molecules like acetamide (CH3CONH2) can be protonated on either their O or N atoms when treated with a strong acid like HCl. Which site is more readily protonated and why?arrow_forwardBb.65.arrow_forward2,4,6-Trinitrophenol is also called picric acid. Why is this substance called an acid? How is the acid strength affected by the substituting groups in this case? H NO₂ O₂N. NO₂arrow_forward
