The freezing point of pure alcohol, lets say ethanol is around -110 to 115 °C which is far below than the freezing point of water, 0 °C. Further the substances added in alcoholic beverages cause depression in freezing point.
So, the refrigerator which works on a high temperature with respect to the freezing point of alcoholic beverages is unable to freeze to form solid, frozen product.
Do the molecular weights for each trial agree closely with each other? If not, discuss the...
Alcoholic beverages are a mixture of water, ethanol, and natural flavoring. Describe why placing an alcoholic beverage in a freezer will not result in a solid, frozen product. (For context, we just finished talking about colligative properties and freezing point depression. :))

i need help with the postlab questions please
Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
