Which of the following is least basic?
Correct answer: A. pyridine
- A. pyridine
- B. piperidine
- C. methyl amine
- D. dimethyl amine
Explanation
The correct basicity order of the following compounds is Dimethyl amine > Methyl amine > Piperidine > Pyridine. The lone pair of electrons are delocalized in the benzene nucleus of pyridine. Hence it becomes the least basic among all.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
