# How do you make one Bromobutane?

## How do you make one Bromobutane?

Global reaction for the synthesis of 1-bromobutane. This halide is easily prepared by reacting butan-1-ol (primary alcohol) with sodium bromide solution and excess of concentrated sulfuric acid. The reaction between sodium bromide and sulphuric acid origins hydrobromic acid (Equation 1).

### What is the density of 1-bromobutane in g mL?

1.276 g/mL at 25 °C (lit.)

What is the density of 2 Bromobutane?

1.26 g/cm³2-Bromobutane / Density

What is the density of 1-butanol g mL?

0.81 g/mL
0.81 g/mL at 25 °C (lit.)

## How do you make 1-bromobutane?

Preparation of 1-bromobutane Place 30 cm3of water, 35 g of powdered sodium bromide and 25 cm3 of butan-1-ol in a 250 cm3round bottomed flask. Fit a tap funnel to the flask via a stillhead.

### What is the density of 1-bromobutane?

On the basis of density; 1-bromobutane has a density of 1.276 g cm -3. Return the 1-bromobutane to the funnel, add about half its volume of concentrated hydrochloric acid, and shake. Run off and discard the lower layer of acid.

How do you determine which layer is the 1-bromobutane layer?

To determine which layer is the 1-bromobutane layer, you take a test tube and add 5 mL of water to it, then  remove a few drops of the bottom layer from the separatory funnel and see if they fall through the water to the bottom.   If they do, the bottom layer is the 1-bromobutane layer or organic layer, if not, the upper

How to prepare concentrated hydrochloric acid from 1-bromobutane?

On the basis of density; 1-bromobutane has a density of 1.276 g cm-3. Return the 1-bromobutane to the funnel, add about half its volume of concentrated hydrochloric acid, and shake. Run off and discard the lower layer of acid. Why is concentrated hydrochloric acid added?
