Write the final product(s) in each of the following reactions :
(a) `CH_(3)-overset(underset(|)(CH_(3)))underset(overset(|)(CH_(3)))(C)-O-CH_(3) + HI to`
(b) `CH_(3)-CH_(2)-underset(overset(|)(OH))(CH)-CH_(3)overset(Cu//573K)(to)`
(c) `C_(6)H_(5)-OHoverset((i) CHCl_(3) + aq. NaOH)underset((ii) H_(.)^(+))(to)`

Explanation

(a) `H_(3)C-underset(overset(|)(CH_(3)))overset(underset(|)(CH_(3)))(C)-O-CH_(3) + HI to H_(3)C-underset(overset(|)(CH_(3)))overset(underset(|)(CH_(3)))(C)-I + CH_(3)OH`
(b) `CH_(3)CH_(2)-underset(overset(|)(OH))(CH)-CH_(3)overset(Cu//573K)(to)CH_(3)CH_(2)-underset(overset(||)(O))C-CH_(3)`
(c)
