How do you prepare alkoxide?
Treat the parent alcohol with an alkali metal; alternatively, treat it with a lithium reagent.
This is applicable to both methanol and ethanol.
As an alternative,
Usually, these alkali metal alkoxides need to be sublimed twice in order to yield the advertised reagent in pure form.

Alkoxides are prepared by reacting an alcohol with a metal, typically an alkali metal such as sodium or potassium, in the presence of a solvent such as tetrahydrofuran (THF) or diethyl ether. The reaction is typically carried out under an inert atmosphere, such as nitrogen or argon, to prevent oxidation of the alkali metal.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
