Using only the reagents KOH (alc. and aq), $\text{Cl}_2$, HBr, acidified $\text{K}_2\text{Cr}_2\text{O}_7$, NaOH and soda lime, carry out the following conversions:
(a)[1.0]
Propanoic acid to Ethanol.
(b)[1.0]
Chloropropane to propan-2-ol.
Answer
Answer (a)
Official answer key$\mathrm{CH_3CH_2COOH \xrightarrow{NaOH} CH_3CH_2COONa \xrightarrow{Soda\ lime} C_2H_6 \xrightarrow{Cl_2} CH_3CH_2Cl \xrightarrow{aq.\ KOH} CH_3CH_2OH}$
Answer (b)
Official answer key$\mathrm{CH_3CH_2CH_2Cl \xrightarrow{alc.\ KOH} CH_3CH=CH_2 \xrightarrow{HBr} CH_3CH(Br)CH_3 \xrightarrow{aq.\ KOH} CH_3CH(OH)CH_3}$
