Why do we use LiCl as a source of chloride ions as nucleophile but not other alkali metal chlorides? [closed]

$$\ce{LiCl}$$ has higher covalent character than other alkali-metal chlorides, so in polar solutions like ethanol, its ioniztion will be less, and so less chloride ions will be available for participating in substitution reaction.

So why don't we use sodium chloride or other alkali metal halides which are more ionic?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

• Could you edit your question to give an example of a reaction that would work with LiCl but not other chlorides, and add why you think it might work with those? Right now, it's unclear what you are asking. – Karsten Theis May 12 at 14:34
