Methods of Preparations of Carboxylic Acids

In the above reaction sequence, the product $\mathrm{C}$ is

The compound $\mathrm{X}$ in the following reaction scheme:

 is:

Nitriles are hydrolysed to amides and then to carboxylic acids in the present of which of the following catalyst:

Grignard reagent reacts with carbon dioxide in diethyl ether followed by acid workup to give a carboxylic acid. It is an example of _____ addition reaction.

When Grignard reagent reacts with dry ice an intermediate compound formed called adduct, which on acid hydrolysis gives ethanoic acid.

Which one of the following functional groups undergoes hydrolysis with alkali to yield an acid group?

A hydrocarbon $\mathrm{A}$ (molecular formula ${\mathrm{C}}_8{\mathrm{H}}_{10}$) on ozonolysis gives $\mathrm{B}$ ( ${\mathrm{C}}_4{\mathrm{H}}_6{\mathrm{O}}_2$ ) only. Compound $\mathrm{C}$ ( ${\mathrm{C}}_3{\mathrm{H}}_5\mathrm{Br}$ ) on treatment with magnesium in dry ether gives $\left(\mathrm{D}\right)$ which on treatment with ${\mathrm{CO}}_2$ followed by acidification gives $\left(\mathrm{B}\right)$ Identify $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$.

Treatment of compound  with $\mathrm{NaOH}$solution yields

How will you convert bromoethane into ethanoic acid ?

Alkyl halides are converted into nitriles by the action of aqueous or aqueous-alcoholic $\mathrm{KCN}$. The reaction follows ${\mathrm{S}}_{\mathrm{N}}2$ mechanism and works best with primary and secondary alkyl halides. Aryl halides are extremely less reactive towards nucleophilic substitutions. Identify the correct procedure for the following conversion.

$2$-Chloroethanol into $3$-hydroxypropanoic acid. 

Alkyl halides are converted into nitriles by the action of aqueous or aqueous-alcoholic $\mathrm{KCN}$. The reaction follows $S{N}^2$ mechanism and works best with primary and secondary alkyl halides. Aryl halides are extremely less reactive towards nucleophilic substitutions. Identify the correct procedure for the following conversion.

tert-butyl bromide into $2,2$-Dimethylpropanoic acid.

Alkyl halides are converted into nitriles by the action of aqueous or aqueous-alcoholic $\mathrm{KCN}$. The reaction follows ${\mathrm{SN}}^2$ mechanism and works best with primary and secondary alkyl halides. Aryl halides are extremely less reactive towards nucleophilic substitution. Identify the correct procedure for the following conversion.

 $2$-Chlorobutane into $2$-Methylbutanoic acid

Alkyl halide are converted into nitriles by the action of aqueous or aqueous-alcoholic $\mathrm{KCN}$.
