Question

What is the product of adding an amine (`RNH_2`) to `HCl`? What about `ArOH+NaHCO_3+NaOH`?

Answer 1

Pl see below

Explanation:

`RNH_2+HCl=RNH_3^+Cl^-`
The amine is basic in nature due its loan pair on N atom . So it donates its loan pair to the electron deficit `H^+` formed by dissociation of HCl as follows
`HCl=H^++Cl^-`

The benzo-phenol is a weak acid (pKa= ~10) and do not react with sodium bicarbonate, which is a weak base itself (pKa(H2CO3)=6.37, 10.3). However, it does react with a strong base like NaOH.as follows
