This causes the alkyl halide to sink to the bottom of the mixture, forming a separate layer from the aqueous layer above. 3. An ether and an alkene are formed as by-products in this reaction. The ether is formed from the dehydration of the alkyl alcohol, which is formed when the alkyl halide reacts with the sodium hydroxide.

The initial product of reaction (1) is carbonic acid (H2CO3) ( H 2 CO 3), which is in equilibrium with water and carbon dioxide gas. This means that solutions of bicarbonate often bubble during a neutralization wash in a separatory funnel. The product of reaction (2) is the bicarbonate ion, which can subsequently undergo reaction (1).

Give equations. Explain what was the purpose of wash using sodium bicarbonate, and why would it be undesirable to wash the crude halide with aqueous sodium …

A) The purpose of washing the crude n-butyl bromide with aqueous sodium bicarbonate is to remove any remaining acid or n-butyl alcohol that might be present in the product. Sodium bicarbonate (NaHCO3) is a weak base that can react with acidic impurities to form water-soluble salts, making it easier to separate them from the organic …

1-butanol has been added, weigh out 12.5 g of solid sodium bromide (NaBr) in a small beaker. Slowly add the solid sodium bromide in small portions. A good way to do this is to crease a piece of weighing paper and use this as a funnel, scraping the solid material into your flask using your spatula. As you add the solid NaBr, swirl
