What are the conditions for nitrobenzene forming phenyl amine?
tin (Sn) concentrated HCl and reflux
1 of 6
What are the conditions for diazotisation? (phenyl amine to benzenediazonium chloride)
NaNO2 (HNO2), HCl and temperatures below 10 degrees
2 of 6
what are the conditions for creating an azo-dye? (from diazonium)
NaOH, phenol and temperatures below 10 degrees
3 of 6
what to primary alcohols oxidise to and what are the conditions?
they first oxidise to aldehydes under distil then under reflux oxidise to carboxylic acids. both reactions happen using a sulphuric acid catalyst and dichromate ions
4 of 6
what to secondary alcohols oxidise to and what are the conditions?
they oxidise to ketones under reflux using a sulphuric acid catalyst and dichromate ions.
