Response: 1-methoxy-2,4-dinitrobenzene
Rationale:
The nitro groups exhibit a strong electron-withdrawing effect, facilitating nucleophilic substitution reactions where a substituent is replaced by a robust nucleophile like the methoxy group. The reaction's mechanism is illustrated below. The electron-withdrawing nature of the nitro group aids in the formation of the intermediate during the reaction as depicted.
Response:
Here's my calculation
Clarification:
Assume the starting concentrations of H₂ and I₂ are 0.030 and 0.015 mol·L⁻¹, respectively.
We need to determine the initial concentration of HI.
1. We will need a chemical equation with concentrations, so let's compile all the information in one location.
H₂ + I₂ ⇌ 2HI
I/mol·L⁻¹: 0.30 0.15 x
2. Calculate the concentration of HI
3. Plot the initial values
The graph below visualizes the initial concentrations as plotted on the vertical axis.
