Explain why P is a stronger base than Q. (P is a secondary amine whilst q is a primary)
M1 The lone pair on nitrogen in P is more available or more able to accept protons/H+ M2 More alkyl groups are electron releasing/donating OR greater (positive) inductive effect (of the alkyl groups).
Identify the reagent that is warmed with isomer W in reaction 2. State the other reaction condition needed.
