Butan-1,3-diol is heated to reflux with potassium dichromate(VI) and sulfuric acid. What functional groups will the product contain?
One aldehyde and one ketone
Two ketones
One ketone and one carboxylic acid
Two carboxylic acids
What best describes the function of anti-bumping granules?
They are anti-bumping
They provide a high surface area, rough surface for rapid nucleation of many bubble to promote smooth, safe boiling
They give the reactant molecules some company
They provide a large surface area, upon which the reaction can occur more quickly
Refluxing allows reactions to reach completion because extended boiling time is provided by the fact that volatile reagents, products and solvents are condensed and returned to the reaction mixture.
True
False
An aldehyde can be prepared from a primary alcohol by distilling the aldehyde product as it forms.
True
False

Add the labels to the diagram of reflux apparatus
Name the product formed when propan-2-ol is heated at reflux with potassium dichromate(VI) and dilute sulfuric acid.
(a)
