Using phenol, dimethyl sulfate, and naoh, show how you would synthesize methyl phenyl ether.
Jlenok [28]
The synthesis of Methyl Phenyl Ether is shown below,

The synthesis takes place in two steps,

Step 1: Formation of Sodium Phenoxide:
                                                                Phenol being more acidic than Alcohols with pKa ≈ 10 can loose its proton attached to oxygen atom, as the resulting phenoxide ion is stabilized by resonance. Therefore, when phenol is treated with NaOH (bBase) it looses proton and forms Sodium Phenoxide.

Step 2: Formation of Methyl Phenyl Ether:
                                                                  The Phenoxide ion formed in first step when treated with Dimethyl Sulfate produces Methyl Phenyl Ether through a Williamson's Ether synthesis Reaction. Dimethyl sulfate is a well known alkylating agent when treated with phenols, thiols and amines. Dimethyl sulfate readily transfers the methyl group and forms NaSO₄CH₃.

The reaction is as follow,

Cómo se denomina el calor que ponen en juego los sistemas materiales cuando cambian su temperatura? Seleccione una: a. Calor cin
Law Incorporation [45]

Answer:

La respuesta correcta es: b. Calor sensible

Explanation:

Al absorber calor, un sistema puede: aumentar su temperatura o cambiar de fase (es decir, pasar de un estado de agregación a otro). Los cambios de fase se producen a temperatura constante, por lo que el calor involucrado se denomina calor latente. Por ejemplo, cuando el agua líquida pasa a vapor por calentamiento a la temperatura de ebullición, esta temperatura se mantiene constante hasta que toda la masa de agua pasa al estado vapor. En cambio, cuando el sistema absorbe calor cambiando su temperatura pero permaneciendo en el mismo estado de agregación (por ejemplo, cuando calentamos agua líquida por debajo de la temperatura de ebullición), el calor involucrado se denomina calor sensible.
