The answer is the first option, <span>∆G is positive.</span><span> </span><span>Endergonic reaction is a chemical reaction where the Gibbs free of energy is positive and there is abosrption of energy. It is a nonspontaneous reaction or unfavorable reaction.</span>
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.

The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.
The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
