An alcohol (P) having molecular formula\( C_4H_{10}O \) undergoes Victor-Meyer's test to give blue colour at the end of reaction when added KOH solution.

i) Draw structure formula and write IUPAC name of (P). 

ii) Write down complete chemical reaction for the Victor-Meyer test of (P). 

iii) How would you prepare (P), starting from \( CH_3MgBr \)? 

iv) What product would you obtain when P is oxidised? 

v) Convert propan-1-ol into propan-2-ol. 

Or

i) Give correct chemical reaction for the preparation of chlorobenzene from: 

a) benzene

b) benzene diazonium chloride

ii) Why is haloarene less reactive than haloalkane towards nucleophilic substitution reactions? 

iii) A reaction sequence is given below.

\( C_6H_5Cl \xrightarrow{(P)} C_6H_6 \xrightarrow{(Q)} C_6H_5CH_3 \xrightarrow{CrO_2 / H^+} (R) \xrightarrow{alc. KCN} (S) \)

a) Write down the reagents and conditions for (P) and (Q). 

b) Draw structural formula of (R) and (S).
