Marks: +1, -0
Write the main product(s) in each of the following reactions:
(i) CH3−C∣CH∣CH3−O−CH3+HI→?\mathrm{CH}_3-\overset{\mathrm{CH}_3}{\overset{\vert}{\underset{\mathrm{CH}}{\underset{\vert}{\mathrm{C}}}}}-\mathrm{O}-\mathrm{CH}_3+\mathrm{HI} \rightarrow?
(ii) CH3−CH=CH2→(ii) 3H2O2/OH−(i) B2H6\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}_2 \xrightarrow[(ii)\,3\mathrm{H}_2\mathrm{O}_2/\mathrm{OH}^-]{(i)\,\mathrm{B}_2\mathrm{H}_6}
(iii)C6H5−OH→(ii) CO2,H+(i) aq.NaOH\mathrm{C}_6\mathrm{H}_5-\mathrm{OH} \xrightarrow[(ii)\,\mathrm{CO}_2,\mathrm{H}^+]{(i)\,\mathrm{aq.NaOH}}
Solution:  
(i) CH3−C∣CH∣CH3−O−CH3+HI→\mathrm{CH}_3-\overset{\mathrm{CH}_3}{\overset{\vert}{\underset{\mathrm{CH}}{\underset{\vert}{\mathrm{C}}}}}-\mathrm{O}-\mathrm{CH}_3+\mathrm{HI} \rightarrow CH3−C∣CH3∣CH3−I−CH3OHMethanolt-butyliodide\underset{\text{t-butyliodide}}{\mathrm{CH}_3-\overset{\mathrm{CH}_3}{\overset{\vert}{\underset{\mathrm{CH}_3}{\underset{\vert}{\mathrm{C}}}}}-\mathrm{I}-\underset{\text{Methanol}}{\mathrm{CH}_3\mathrm{OH}}}
(ii) CH3−CH=CH2→(ii) 3H2O2/OH−(i) B2H6\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}_2 \xrightarrow[(ii)\,3\mathrm{H}_2\mathrm{O}_2/\mathrm{OH}^-]{(i)\,\mathrm{B}_2\mathrm{H}_6} CH3CH2CH2OH\mathrm{CH_3CH_2CH_2OH}
