Paso 1: Determinar los electrones de valencia totales.

El carbono tiene 4 electrones de valencia, cada hidrógeno tiene 1 y cada cloro tiene 7. Por lo tanto, CH₂Cl₂ tiene un total de 4 + 2(1) + 2(7) = 20 electrones de valencia.

Paso 2: Dibujar el esqueleto de la molécula.

El carbono es el átomo central menos electronegativo, por lo que va en el centro. Los hidrógenos y cloros se unen al carbono.

Paso 3: Distribuir los electrones restantes.

Primero completamos los octetos de los átomos más electronegativos (los cloros). Luego, colocamos los electrones restantes alrededor del carbono.

Respuesta final:

La segunda opción es la correcta:

 H
