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 CH2\text{CH}_2 next to a CH3\text{CH}_3 is a quartet because of the three neighbours.
What are RfR_f depends on conditions?
Show answer
A retention factor is only comparable under the same solvent and plate; quoting an absolute RfR_f 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]
