?

Answer:
Conjugate base of naphthol is highly stable but conjugate base of ethanol is unstable.
Explanation:
Naphthol gives acid base reaction with NaOH where naphthol acts as an acid and NaOH as a base.
Reactivity of naphthol towards NaOH is quite high because the conjugate base of naphthol is highly stable. Stability of the conjugate base arises due to delocalization of negative charge on oxygen atom into aromatic naphthalene ring.
Ethanol is not so reactive towards NaOH because the ethoxide ion is highly unstable due to lack of delocalization of negative charge on oxygen atom.
Resonance structures of conjugate base of naphthol has been shown below.

Answer:
Explanation:
We classify the behaviours of electrolytes based on their electrolytic conduction. This is what makes them breaks down when in aqueous solutions with water.
A strong electrolyte is one that ionize completely when in aqueous solutions. Their ionization can be shown below using appropriate chemical notation:
An example of a strong electrolyte is NaCl:
NaCl → Na⁺
+ Cl⁻
Such reactions have a single forward arrow. Since they ionize complete, they have a large amoung of ions present in their aqueous form and would readily conduct.
A weak electrolyte is made up of compounds that ionize partially or slightly in their aqueous solution. The amount of ions produced per mole of compounds is relatively small compared to those of strong electrolytes. Examples ae organic acids, weak bases, and water. This ionization is shown below for methanoic acid:
HCOOH ⇄ HCOO⁻
+ H⁺
This sort of reaction is an equilibrium reaction. This is why we have the double arrow.
None electrolytes do not ionize at all in aqueous solutions and they produce no ions.
