In how many reactions `CO_(2)` gas is released out after reaction with `NaHCO_(3)`
(1) `CH_(3)-underset(O)underset(||)overset(O)overset(||)(S)-O-H+NaHCO_(3) rarr`
(2) `CH_(3)-underset(O)underset(||)(C)-O-H+NaHCO_(3) rarr`

`CH_(3)-CH_(2)-OH+NaHCO_(3) rarr`
(5) `CH_(3)-C-=C-H+NaHCO_(3) rarr`

Answer

2

Explanation

(1) `CH_(3)-underset(O)underset(||)overset(O)overset(||)(S)-O-H+NaHCO_(3) rarrCH_(3)-underset(O)underset(||)overset(O)overset(||)(S)-overset(Θ)(O)overset(o+)(Na)+H_(2)O+CO_(2)uarr`
(2) `CH_(3)-underset(O)underset(||)(C )-O-H+NaHCO_(3) rarrCH_(3)-underset(O)underset(||)(C)-overset(Θ)(O)-overset(o+)(Na)+H_(2)O+CO_(2)uarr`

(4) `CH_(3)-CH_(2)-OH+NaHCO_(3) rarr (-ve)`
(5) `CH_(3)-C-=C-H+NaHCO_(3) rarr (-ve)`
