Respuesta :
The Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
To determine which is the Brønsted-Lowry base in the given reaction:
NH2−+CH3OH→NH3+CH3O−
First, we will write the equation for the reaction properly
The equation is:
NH₂⁻ + CH₃OH → NH₃ + CH₃O⁻
Now, to determine which among the species in the above reaction is the Brønsted-Lowry base, we will start by defining what a Brønsted-Lowry base is.
A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H⁺.
In simple terms, a Brønsted-Lowry base is a proton acceptor.
In the above reaction, NH₂⁻ is the species that is capable of accepting a proton and it has a lone pair of electrons to bond to the H⁺.
∴ NH₂⁻ is the Brønsted-Lowry base in the reaction
Hence, the Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
