Q. Increasing reactivity order of nucleophilic addition reaction of $ H-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-H;C{{H}_{3}}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-H $ and $ C{{H}_{3}}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}} $ will be

Solution:
Reactivity of nucleophilic addition reaction depends upon carboniumion
. On increasing stability, reactivity decreases. Hence, decreasing order of reactivity is:
$ +I $ effect of $ C{{H}_{3}} $ group decreases reactivity of
.
