Question
Which of the following statements is true regarding pyridine?Select answer from the options belowAll of the lone pairs of electrons in pyridine participate in resonance delocalization.Pyridine can function as a base.Pyridine has a five-membered ring.Pyridine is antiaromatic.
Solution
The true statement regarding pyridine is: "Pyridine can function as a base."
Here's why:
-
"All of the lone pairs of electrons in pyridine participate in resonance delocalization." - This statement is false. In pyridine, one of the nitrogen's lone pairs of electrons is not involved in resonance because it is in an sp2 hybridized orbital and is perpendicular to the plane of the molecule.
-
"Pyridine can function as a base." - This statement is true. Pyridine can act as a base because it has a lone pair of electrons that can be donated. It is a weak base.
-
"Pyridine has a five-membered ring." - This statement is false. Pyridine has a six-membered ring with one nitrogen and five carbon atoms.
-
"Pyridine is antiaromatic." - This statement is false. Pyridine is not antiaromatic; it is aromatic because it follows Hückel's rule of 4n+2 π electrons (n=1).
