Marks: +1, -0
Write the final product(s) in each of the following reactions :
(a) CH3−CCH∣3CHC∣3−O−CH3+HI→,\mathrm{CH}_3 - \overset{\mathrm{CH}{\overset{\vert}{\mathrm{C}}}_3}{\underset{\mathrm{CH}{|}_3}{\mathrm{C}}} - \mathrm{O} - \mathrm{CH}_3 + \mathrm{HI} \rightarrow ,
(b) CH3−CH2−CH∣OH−CH3→Cu/573 K\mathrm{CH}_3 - \mathrm{CH}_2 - \underset{\mathrm{OH}}{\underset{\vert}{\mathrm{CH}}} - \mathrm{CH}_3 \xrightarrow{\mathrm{Cu} / 573 \, \mathrm{K}},
(c) C6H5−OH→(ii) H+(i) CHCl3+aq. NaOH\mathrm{C}_6 \mathrm{H}_5 - \mathrm{OH} \xrightarrow[(ii)\,\mathrm{H}^{+}]{(i)\,\mathrm{CHCl}_3 + \mathrm{aq.}\,\mathrm{NaOH}}
Solution:  
(a) CH3−CCH∣3CHC∣3−O−CH3+HI→\mathrm{CH}_3 - \overset{\mathrm{CH}{\overset{\vert}{\mathrm{C}}}_3}{\underset{\mathrm{CH}{|}_3}{\mathrm{C}}} - \mathrm{O} - \mathrm{CH}_3 + \mathrm{HI} \rightarrow CH3−CCH∣3CHC∣3−I+CH3I+H2O2-Iodo-2-methylpropane\underset{\text{2-Iodo-2-methylpropane}}{\mathrm{CH}_3 - \overset{\mathrm{CH}{\overset{\vert}{\mathrm{C}}}_3}{\underset{\mathrm{CH}{|}_3}{\mathrm{C}}} - \mathrm{I} + \mathrm{CH}_3 \mathrm{I} + \mathrm{H}_2 \mathrm{O}}
(b) CH3−CH2−CH∣OH−CH3→Cu/573 K\mathrm{CH}_3 - \mathrm{CH}_2 - \underset{\mathrm{OH}}{\underset{\vert}{\mathrm{CH}}} - \mathrm{CH}_3 \xrightarrow{\mathrm{Cu} / 573 \, \mathrm{K}} CH3−CH2−C∥O−CH3+H2Butanone\underset{\text{Butanone}}{\mathrm{CH}_3 - \mathrm{CH}_2 - \underset{\mathrm{O}}{\underset{\parallel}{\mathrm{C}}} - \mathrm{CH}_3 + \mathrm{H}_2}
