¿If5 es polar o no polar?
Respuesta: IF5 es unMolécula polardebido a la presencia de un par solitario de electrones que, debido a la repulsión electrón-electrón, da como resultado una estructura plegada.
Pentafluoruro de yodo (SE5) es unMolécula polar. El átomo central de yodo (I) en IF5está rodeado por cinco átomos de flúor (F) que forman una forma piramidal cuadrada. La electronegatividad del átomo de flúor (F) es mayor que la del átomo de yodo (I).
Respuesta y explicación:El pentafluoruro de yodo tiene un momento dipolar., que es una medida de su polaridad.
SE5contiene cinco dominios de electrones enlazados y uno no enlazado, dando unaoctaédrico y-geometría de dominio y una geometría molecular piramidal cuadrada(MACHADO5Y). Los ángulos de enlace están comprimidos en relación con un octaedro perfecto porque el par solitario está más disperso en el espacio que los pares enlazados.
IF3 es unMolécula polardebido a la diferencia de electronegatividad entre los átomos I y F.
Para determinar si una molécula es polar o no polar, suele ser útil observar las estructuras de Lewis.Los compuestos no polares serán simétricos, lo que significa que todos los lados alrededor del átomo central son idénticos, unidos al mismo elemento sin pares de electrones no compartidos..
¿Qué opción describe mejor la polaridad del IF5?La molécula es polar y tiene enlaces polares..
IF5 está estructurado como beta y cristaliza en el grupo espacial monoclínico C2/c. La estructura es de dimensión cero y consta de veinte grupos IF5. I5+ está unido en una geometría piramidal cuadrada a cinco átomos F1-. Hayuna longitud de enlace I-F más corta (1,85 Å) y cuatro más largas (1,93 Å).
SE5es d2sp3hibridado y contiene1 pareja solitariay 5 pares de enlaces de electrones de valencia alrededor del yodo. El VSEPR predice la forma de pirámide cuadrada.
Después de determinar cuántos electrones de valencia hay en IF5, colóquelos alrededor del átomo central para completar los octetos. hay un total de42 valenciapara la estructura de Lewis para IF5.
¿Por qué el IF5 es no polar?
Respuesta: IF5 es una molécula polardebido a la presencia de un par solitario de electrones que, debido a la repulsión electrón-electrón, da como resultado una estructura plegada. Esto conduce a una distribución desigual de la carga dentro de la molécula y, por lo tanto, a un dipolo permanente.
El átomo de yodo del trifluoruro de yodo tiene cinco pares de electrones, de los cuales dos son pares solitarios, y la molécula esme forma de Tcomo previsto pela teoria VSEPR.
Las moléculas polares se producen cuando hay una diferencia de electronegatividad entre los átomos enlazados.. Las moléculas no polares ocurren cuando los electrones se comparten por igual entre los átomos en una molécula diatómica o cuando los enlaces polares en una molécula más grande se anulan entre sí.
Ejemplos de moléculas polares sonHCl, H2O, NH3, y el de las moléculas no polares son H2,O2,Cl2.
Cuando los átomos se unen para formar moléculas, comparten o donan electrones.Si los átomos comparten los electrones por igual, entonces no hay carga neta., y la molécula es no polar.
Ejemplos de moléculas no polares
Ejemplos de moléculas no polares homonucleares sonoxígeno (O2), nitrógeno (N2) y ozono (O3). Otras moléculas no polares incluyen dióxido de carbono (CO2) y las moléculas orgánicas metano (CH4), tolueno y gasolina.
| Diferencia entre polar y no polar | |
|---|---|
| POLAR | NO POLAR |
| Tiene postes eléctricos. | No tiene postes eléctricos. |
| Un extremo de la molécula tiene carga positiva, mientras que el otro extremo tiene carga negativa. | No tiene profusión de cargas en extremos opuestos. |
| Al menos un covalente polar está presente en todas las moléculas polares. | |
Las moléculas polares tienen una distribución uniforme de densidad de electrones. Una molécula no polar resulta de una distribución desigual de la densidad de electrones.. Los compuestos polares están dispuestos asimétricamente. Tienen enlaces polares que son simétricos.
Respuesta experta
La molécula de PF5 tiene una geometría bipiramidal trigonal que hace que los enlaces opuestos cancelen el momento dipolar del otro.El pentafluoruro de fósforo es una molécula no polar.debido a la estructura simétrica y la distribución uniforme de cargas en la molécula.
Por ejemplo, el pentafluoruro de yodo (IF5) se usa ampliamente enproducción de yoduros de alquilo que contienen flúor, intermediarios valiosos en la síntesis de compuestos perfluoro-orgánicos. Estos se utilizan para producir emulsiones repelentes al agua y al aceite para el tratamiento de textiles y cuero y para espumas extintoras de incendios.
