In the third step of the synthesis there are two different nucleophilic heteroatoms available for reaction with the acetic anhydride. First, draw the product that would have formed if the other heteroatom had reacted with the acetic anhydride. Secondly, indicate what data was used to choose which of these heteroatoms reacted. Finally, chemically explain why one of the heteroatoms reacts in preference to the other one.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
