What are the n+1 rule applies to neighbours?Show answer
Splitting comes from the hydrogens on adjacent carbons, not the hydrogens within the same group; a next to a is a quartet because of the three neighbours.
What are depends on conditions?Show answer
A retention factor is only comparable under the same solvent and plate; quoting an absolute without the conditions is meaningless.
What is q1?Show answer
State what the integration (relative peak areas) in a proton NMR spectrum tells you. [1 mark]
What is q2?Show answer
A hydrogen environment shows a triplet in the proton NMR spectrum. How many hydrogens are on the adjacent atom(s)? [1 mark]
