Explanation Limiting reactant: The reactant that limits the amount of product is called the limiting reactant. It decides the maximum quantity of a product in the reaction. The reactant that produces a lesser amount of product is the limiting reactant. Theoretical yield: The calculated yield based on the amount of limiting reactant is called the theoretical yield. Thus, this gives the exact amount of product that should come out as a result of a chemical reaction . Percent yield: The percentage of theoretical yield that actually results from a chemical reaction is called the percent yield. The actual yield may vary from the theoretical yield as some product may not be formed or it may convert to some other state that is omitted from calculation. Thus, percent yield = ( a c t u a l y i e l d t h e o r e t i c a l y i e l d ) × 100 Molar mass of Mg = 24 Molar mass of O = 16 Formula molar mass = m

Does the carbonyl group first react with the ethylene glycol, in an intermolecular reaction, or with the end alcohol, in an intramolecular reaction, to form a hemiacetal? Why does it react with the alcohol it does first rather than the other one? Please do not use an AI answer.
