(i) `NH_(3)` , (ii) `CH_(3)NH_(2)`
(iii) `HCO_(3)^(-)` , (iv) `SO_(4)^(2-)`

A

(i), (ii), (iii), (iv)

B

(i), (ii)

C

(i), (ii), (iv)

D

(ii), (iii), (iv)

Text Solution

Verified by Experts

The correct Answer is:
A
A Brostend base is any species that can accept a proton `(H^(+))`. It could be neutral or charged.
`overset(..)(N)H_(3)+H^(+)rarrNH_(4)^(+)`
`CH_(2)overset(..)(N)H_(2)+H^(+)rarr CH_(3)overset(+)(N)H_(3)`
`HCO_(3)^(-)+H^(+)rarr H_(2)CO_(3)`
`SO_(4)^(2-)+H^(+)rarr HSO_(4)^(-)`
