What happens when pyridine reacts with HCl?

Answer: pyridine reacts readily with HCl to form pyridinium chloride, while pyrrole is rather unreactive.

What happens when you mix NaOH and HCl?

Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release of heat. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water – compounds that are ultimately harmless, even beneficial, to human beings.

Is pyridinium a strong acid?

This means that pyridinium is a weak acid. Note that this is the Kb reaction for chloride. At this point it seems we have two reactions (the Kb reaction for pyridine producing pyridinium and hydroxide being one, the Ka reaction for pyridinium producing pyridine and hydronium being the other) that describe the system.

What happens when HCL is mixed with pyridine?

In presence of pyridine, HCl generated does not leave the reaction mixture (as above), but reacts with pyridine to yield pyridinium chloride. Pyridinium chloride is able to react along SN2 on the alkyl chlorosulfite. Seeing this variant from the beginning till the SN2 of the alkyl chlorosulfite yields the inversion of configuration observed.

Why is pyridine able to react along SN2?

Pyridinium chloride is able to react along SN2 on the alkyl chlorosulfite. Seeing this variant from the beginning till the SN2 of the alkyl chlorosulfite yields the inversion of configuration observed. Thanks for contributing an answer to Chemistry Stack Exchange!

What is the structure of pyridine as a base?

This system has appreciable quantities of both pyridine (Py) and pyridinium chloride. The structure of pyridine is shown below and is a base. As a base it could undergo the following reaction (note that this is the K b reaction). (1) Py + H 2 O ↔ PyH + + OH −

How to make pyridine from N-oxides?
