Hey guys,



Really struggling with a section of questions on Alcohols, and would be extremely grateful for any assistance anyone may be able to give!



You are given two samples of alcohol 1-Butanol which reacts with acidified potassium dichromate K2Cr2O7/H+ under different conditions to produce two products.

Describe the conditions required to produce the different products, giving the names and structural formulae of the products produced and equations to summarise the reactions involved

Name and state the structural formula of the product that would result from treating 2-Butanol with acidified potassium dichromate (K2Cr2O7/H+) and heating under reflux and using the same reagent, describe how to distinguish between alcohols 1-Butanol, 2-Butanol and 2-methly-2-propanol.

Esters can be synthesised in the reaction between alcohols and carboxylic acids in a reaction called esterification.

Ethanol reacts with propanoic acid, name the product of the reaction with its structural formula.

Potassium dichromate is an oxidisating agent.

You should check your textbook about the oxidation of alcohols.
There is a difference in the reactions of primary, secondary and tertiary alcohols.

Primary alcohols yield first aldehydes on oxidation, then carboxylic acids on further oxidation.

Secondary alcohols yield ketones.

Tertiary alcohols are generally unreactive.

Esterification reactions are a different type of reaction.
