Vedclass · Answer

(B) $1$. Hydroboration-oxidation of propene $(CH_3-CH=CH_2)$ follows anti-Markovnikov addition to yield propan$-1-$ol $(P = CH_3-CH_2-CH_2-OH)$.$2$. Oxidation of primary alcohol $(P)$ with $CrO_3$ in anhydrous medium stops at the aldehyde stage, yielding propanal $(Q = CH_3-CH_2-CHO)$.$3$. Reaction of propanal $(Q)$ with methylmagnesium bromide $(CH_3MgBr)$ followed by acid hydrolysis yields butan$-2-$ol $(R = CH_3-CH_2-CH(OH)-CH_3)$.

Identify the organic compounds $P$, $Q$, and $R$ in the following reaction sequence: $C_3H_6 \xrightarrow[ii) H_2O_2/NaOH]{i) BH_3} P \xrightarrow[anhydrous medium]{CrO_3} Q \xrightarrow[ii) H_3O^+]{i) CH_3MgBr} R + Mg(OH)Br$.
