Marks: +1, -0

Write the main product(s) in each of the following reactions:
(i)

{\CH}_3- {\C}↖{|}↖{\CH_3} ↙{|} ↙{\CH}- {\O}- {\CH}_3+ {\HI} \ {────▸}?

(ii)

{\CH}_3- {\CH}= {\CH}_2 \ {────▸}↖{(\i) \B_2\H_6}↙{(\ii)3 {\H}_2 {\O}_2 \/ {\OH}^{-}}

(iii)

{\C}_6 {\H}_5- {\OH} \ {────▸}↖{ (\i) {\aq.\NaOH}}↙{ (\ii) {\CO_2,\H^{+}}}

Solution:

(i)

{\CH}_3- {\C}↖{|}↖{\CH_3} ↙{|} ↙{\CH}- {\O}- {\CH}_3+ {\HI} \ {────▸}

{ {\CH}_3- {\C}↖{|}↖{\CH_3} ↙{|} ↙{\CH_3}- {\I}-{ {\CH}_3\OH}↙{\Methanol} }↙{t-\butyliodide}

(ii)

{\CH}_3- {\CH}= {\CH}_2 \ {────────▸}↖{(\i) \B_2\H_6}↙{(\ii)3 {\H}_2 {\O}_2 \/ {\OH}^{-}}

\CH_3\CH_2\CH_2\OH
