What is/are the principal product(s) formed when excess methylmagnesium iodide reacts with p-hydroxyacetophenone?
Montano1993 [528]

The end product will depend upon

a) the amount of the reagent taken

b) the final treatment of the reaction

If we have just taken methylmagnesium iodide and p-hydroxyacetophenone, then we will get methane and hydroxyl group substituted with MgI in place of hydrogen

Figure 1

However if we have taken excess of methylmagnesium iodide which is Grignard's reagent followed by hydrolysis we will get different product

Figure 2

What's wrong with this thermochemical equation?
mafiozo [28]

This thermochemical equation needs to be balanced. Hence, option B is correct.

<h3>What is a balanced chemical equation?</h3>

A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.

The balanced thermochemical equation is:

H_2(g) + 2NaCl (s) + 3O_2 (g) → 2HCl (l) + 2Na (s) + 2O_3 (g)

Hence, option B is correct.
