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.
