Two moles of `PCl_(5)` were heated at `327^(@)C` in a closed two litre vessel and when equilibrium was reached, `PCl_(5)` was found to be 40% dissociated into `PCl_(3)` and `Cl_(2)` The equilibrium constant `K_(rho)` for the above reaction is (approx)A. 13.14 `atm^(-1)`B. 13.14 atmC. 6.52 atmD. 6.52 `atm^(-1)` |

Answer» Correct Answer - D `-underset(..)overset(..)(O)-CH_(3)` increases the `e^(-)` density in ring due to +M. `-underset(..)overset(..)(O)-H` increases the `e^(-)` density in ring due to +M. `-underset(..)overset(..)(O)-overset(O)overset(||)(C)-CH_(3)` increases the `e^(-)` density in ring due to +M. -CN is a strong `e^(-)` withdrawing group, so it decreases the `e^(-)` density from the ring. |
