Answer 1

The given question is incomplete. The complete question is :

In each row check off the boxes that apply to the underlined reactant. The underlined reactant acts as a... (check all that apply)

1.
`HCH_3CO_2(aq)+NH_3(aq)\rightarrow CH_3COO^-(aq)+NH_4^+(aq)`

here underlined is
`HCH_3CO_2`

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

2.
`BH_3(aq)+NH_3(aq)\rightarrow BH_3NH_3(aq)`

Here underlined is
`NH_3`

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

3.
`HNO_2(aq)+C_2H_5NH_2(aq)\rightarrow NO_2^-(aq) + C_2H_5NH_3^+(aq)`

Here underlined is
`C_2H_5NH_2`

A. Brønsted-Lowry acid

B. Brønsted-Lowry base

C. Lewis acid

D. Lewis base

Answer: 1. Brønsted-Lowry acid

2. Lewis base

3. Brønsted-Lowry base

Step-by-step explanation:

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

1.
`HCH_3CO_2(aq)+NH_3(aq)\rightarrow CH_3CO^(2-)(aq)+NH_4^+aq)`

As
`HCH_3CO_2(aq)` is donating a proton , it acts as a bronsted acid.

2.
`BH_3(aq)+NH_3(aq)\rightarrow BH_3NH_3(aq)`

As
`NH_3` contains a lone pair of electron on nitrogen , it can easily donate electrons to
`BH_3` and act as lewi base.

3.
`HNO_2(aq)+C_2H_5NH_2(aq)\rightarrow NO_2^-(aq) + C_2H_5NH_3^+(aq)`

As
`C_2H_5NH_2(aq)` is accepting a proton , it acts as a bronsted base.
