Why will the reaction fail to work if the phase transfer catalyst is switched to ammonium chloride while retaining the same reactants, solvent, and base? Because it reacts with 2‑naphthol to make 2‑chloronaphthalene. Because it generates a powerful nitrogen‑based nucleophile in aqueous base. Because ammonium chloride is not soluble in dichloromethane solvent. Because ammonium chloride is not soluble in water.

Because ammonium chloride is not soluble in dichloromethane solvent.

Explanation:

It looks like you are trying to do a Williamson ether synthesis using 2-naphthol, allyl chloride, and a phase transfer catalyst like benzyltriphenylammonium chloride.

The phase transfer catalyst is soluble in dichloromethane and carries the alkoxide ions with it into the organic phase. This is where the reaction takes place.

If, instead, you use ammonium chloride, the reaction will fail.

NH₄Cl is a polar ionic solute. It is soluble in the polar aqueous phase but insoluble in the much less polar dichloromethane.

A is wrong. Naphthols do not undergo displacement reactions.

B is wrong. NH₄Cl generates the weak base NH₃ in aqueous NaOH.

D is wrong. Ammonium salts are soluble in water.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
