Write the main product(s) in each of the following reactions :
(i) `CH_(3)-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")"C "-O-CH_(3)+Hirarr`
(ii) `CH_(3)-CH=CH_(2)overset((i)B_(2)H_(6))underset((ii)3H_(2)O_(2)//OH^(-))rarr`
(iii) `C_(6)H_(5)-OH overset((i)aq. NaOH)underset((ii)CO_(2), H^(+))rarr`
