Acierta si es verdad o mentira.

1

La SEAr de un heterociclo aromático de 5 miembros sin ningún sustituyente se ve favorecida en la posición 2 debido al efecto inductivo

2

La SEAr en el benzofurano se ve favorecida en la posición 3 ya que a pesar de tener menos estructuras resonantes , no se pierde la aromaticidad

3

El furano puede actuar como base ya que los electrones no compartidos del oxígeno no contribuyen a la aromaticidad del compuesto

4

Si se quiere hacer una SNAr en la posición 3 ( o 5) de la piridina, una buena opción es antes de este paso realizar una oxidación sobre el nitrógeno

5

La piridina con un halógeno como sustituyente en la posición 2, cuando reacciona con un núcleofilo se favorece la sustitución del halógeno por dicho núcleofilo

6

El compuesto es aromático
