A drop of a solution (volume 0.05 mL) contains 3.0xx10^(-6) mole of H^(+) ions. If the rate constant of disappearance of H^(+) ions is 1.0xx10^(-7)" mol L"^(-1)s^(-1), how long would it take for H^(+) ions in the drop to disappear ?

Answer»

Solution :As the units of RATE constant are `"mol L"^(-1)s^(-1)`, this means disappearance of `H^(+)` ions is a reaction of zero order. For `100%` reaction to COMPLETE (i.e., complete disappearance of `H^(+)` ions)
`t_(100%)=([A]_(0))/(K)=([H^(+)])/(k)`
0.05 mL of the DROP contains `H^(+)` ions `=3.0xx10^(-6)` mole
`:.100" mL of the solution will contain "[H^(+)]=(3.0xx10^(-6))/(0.05)xx1000=6xx10^(-2)`
i.e., `[H^(+)]=6xx10^(-2)" M"`

(a) Discuss the important physical properties of carboxylic acids. (b) Discuss the structure of carboxylic acids. How do you account for acidic character of carboxylic acids ?

Answer»

Solution :(a) Physical properties of carboxylic acids. The important physical properties of carboxylic acids are given ahead :
(i) The FIRST three members of the carboxylic acids are colourless and have pungent smell. The next six members are oily liquids with a faint unpleasant odour. Thereafter, they are colourless waxy solids. Benozic ACID and its homologues are colourless solids.
(ii) The first four members are very soluble in water and the solubility decreases gradually with the rise of molecular mass. However, all are soluble in alcohol or ether. Benzoic acid is sparingly soluble in cold water but is soluble in hot water, alcohol, ether.
(iii) Lower carboxylic acids (upto `C_(10)`) are volatile in steam while higher members are non-volatile.
(iv) They have higher boiling points than the corresponding alcohols of COMPARABLE molecular masses. This is due to the fact that a pair of carboxylic acid molecules (known as dimers) are held together not by one but by two hydrogen bonds :

(b) Structure of carboxylic acids. Carboxylic acid is planar molecule in which the carbon atom of carbonyl group is `sp^(2)` hybridised. It is bonded to the oxygen atom of OH group and the carbon atom (or H atom) with the help of `sigma` bonds. It is a resonance hybrid of the following structures :

It is clear that in the resonance hybrid (structure II) the oxygen atom of a hydroxyl group carries some positive charge. Consequently, the ELECTRON pair of the O-H bond is displaced towards oxygen atom. This displacement of electron causes the release of a proton and a carboxylate ion, `RCOO^(-)`, is formed.
 Carboxylate ion The carboxylate ion thus formed is also a resonance hybrid of structures III and IV as shown below :
Thus, we observe that carboxylic acid as well as its anion are resonance stabilised. However, we compare these structures, we observe that carboxylic acid stabilised) structures (I and II) are not cquivalent while carboxylate ion structures (III and IV) are equivalent. Therefore, the carboxylate ion is more resonance stabilised by the resonance. Thus, carboxylic acids READILY give proton to form more stable carboxylate ion.

(e ) Compare the following alkyl halides in decreasingorder of reactivity in the Williamson's reaction : ClCH_(2)CH_(2)CH_(3)(A),""BrCH_(2)CH_(2)CH_(3)(B), (CH_(3))_(3)C C H_(2)Br(C ),""ClCH_(2)CH=CH_(2)(D) (f) Give six types of ethers and cannot be synthesised by the typical Williamson's reaction.

Answer»

Solution :[Hint]
(i) Alcohols and ethers may be regarded as derivatives of H-O-H . The replacement of one H atom affords alcohols, ROH. In ethers both hydrogen atoms are replaced.
(ii) In all the three cases, oxygen undergoes `sp^(3)` -hybridization, there is contraction in the bond angle , which is `105^(@)`. The bond angle is very close to `109^(@)`in alcohols. The C-O-C bond angle in ethers is about `110^(@)` on account of repulsive van der Waals' forces between groups of larger size.
(iii)The heterocyclic polyether is called crown ether. It is named on the basis of total number of atoms in the ring and number of oxygen atoms. [15] crown -5 MEANS 15 atoms inthe ring including 5 oxygen atoms.
(iv) Absolute ether means diethyl ether absolutely free from water.

(a) Discuss briefly the following reactions : (i) Gattermann Koch reaction (ii) Rosenmund reaction.  (b) Trichloro acetic acid is stronger acid than dichloro acetic acid. Explain.

Answer»

Solution :(a) (i) Gattermann Koch reaction. BENZENE on passing through a mixture of carbon monoxide and hydrochloric acid gas in the presence of anhydrous `AICI_(3)` and traces of cuprous chloride is converted to benzaldehyde by this reaction.

It is modified form of Friedel-Crafts reaction in which -CHO GROUP is introduced in the benzene ring.
(II) Rosenmund.s reaction. Acid chloride on reacting hydrogen in the presence of palladium suspended over barium SULPHATE and poisoned with sulphur or quinoline gets converted to an aldehyde by this reaction.

`CH_(3)COCl+H_(2) overset(Pd. BaSO_(4))to underset("Ethanol")(CH_(3)CHO)+HCl`
(b)

Due to the presence of more number of electron withdrawing groups in trichloroacetic than dichloroacetic acid, the-Inductive effect causes the electron withdrawal more strongly towards oxygen of O-H bond and promotes the release of `H^(+)` ions more effectively. Thus trichloroacetic is more acidic than dichloro acetic acid.
