Question : 17 of 26

Marks: +1, -0

Write the final product(s) in each of the following reactions :
(a)

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

(b)

{\CH}_3- {\CH}_2- {\CH}↙{|}↙{\OH}- {\CH}_3 \ {─────▸}↖{ {\Cu} \/ 573 {\K}}

,
(c)

{\C}_6 {\H}_5- {\OH} \ {─────────▸}↖{(\i) {\CHCl}_3+ \aq. {\NaOH}}↙{(\ii)\ {\H}^{+}}

Solution:

(a)

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

{ {\CH}_3- {\C}↖{|}↖{{\CH}_3}↙{|}↙{{\CH}_3}- {\I}+ {\CH}_3 {\I}+ {\H}_2 {\O}}↙{\text "2-Iodo-2-methylpropane "}

(b)

{\CH}_3- {\CH}_2- {\CH}↙{|}↙{\OH}- {\CH}_3 \ {─────▸}↖{ {\Cu} \/ 573 {\K}}

{ {\CH}_3-{\CH}_2-\;{{ {\C}}}↙{ ∥}↙ {\O} - {\CH}_3+ {\H}_2}↙{\Butanone}
