Answer: They are referred to as isotopes, which are a form of an element that has different numbers of neutrons in their nucleus.
The procedural steps in order to get iodinate salicylamide are as follows:
- It begins first at a laboratory.
- Secondly, one has to dissolve salicylamide in ethanol.
- Then one has to add sodium iodide.
- Later on, one has to add sodium hypochlorite to the ice cold solution of salicylamide and sodium iodide.
- Thereafter one has to sodium thiosulfate.
- It is better to Acidify by a person adding about 10% of HCl.
- The one has to collect the crude product through the use of vacuum filtration.
- Lastly one then Recrystallize from hot ethanol.
<h3>What is Electrophilic aromatic substitution?</h3>
The Electrophilic aromatic substitution is known to be a kind of an organic reaction where an atom is said to be added or attached to a kind of aromatic structure (that is made up of hydrogen) is said to be replaced by an electrophile.

Answer:-
Option 2
Explanation:-
In a multi step reaction, the overall reaction is as fast as the slowest step only.
So the rate of a multistep reaction is the same as the rate of its slowest step.
The gas phase reaction was found to be second order wrt NO2.
So the slowest step must have 2 NO2 since the dependence is second order on NO2.
It was also found to be zero order wrt CO.
So the slowest step must not contain any CO since it’s presence has no effect on the reaction (zero order).
Among all options, only number 2 meets the two criterion
Thus the steps are
NO2 + NO2 – NO3 + NO (Slow)
NO3 + CO – NO2 + CO2 (Fast)
