Isoquinoline is more basic than quinoline due to the presence of an extra nitrogen atom in the heterocyclic ring. This extra nitrogen can accept a proton more readily, making isoquinoline more basic. The lone pair of electrons on the additional nitrogen atom is more available for protonation compared to the lone pair on the nitrogen in quinoline.
Pyridine is more basic than quinoline. This is because the nitrogen atom in pyridine is more readily available to accept a proton compared to the nitrogen in quinoline due to the presence of an additional ring in quinoline which delocalizes the lone pair of electrons on the nitrogen atom, making it less basic.
Quinoline "poisons" the Lindlar catalyst, thereby enhancing its selectivity. This prevents the hydrogenation reaction from going from the alkyne to the alkane, and instead from the alkyne to the alkene.
The highest pH is basic. pH measures the acidity or basicity of a solution on a scale of 0 to 14, with pH values above 7 considered basic. A pH of 14 is the most basic, indicating a high concentration of hydroxide ions.
Milk of magnesia contains MgO. It is more basic than NH3.
arginine is more basic due to the presence of 3 NH2 groups
Pyridine is more basic than quinoline. This is because the nitrogen atom in pyridine is more readily available to accept a proton compared to the nitrogen in quinoline due to the presence of an additional ring in quinoline which delocalizes the lone pair of electrons on the nitrogen atom, making it less basic.

A benzyltetrahydroisoquinoline is an isoquinoline which is used in the production of analgesics such as morphine, codeine and thebaine.

Isoquinoline alkaloids including sanguinarine which has bacteria inhibiting properties.
An aporphine is a member of a class of quinoline alkaloids from which apomorphine can be derived.
An aminoquinoline is any of various quinoline derivatives notable as antimalarial drugs.
A bisquinoline is any of a family of antimalarial drugs with a structure involving two quinoline groups in a compound.
Quinoline does not undergo Friedel-Crafts reactions primarily due to the presence of the nitrogen atom in its structure, which is a strong electron-withdrawing group. This nitrogen decreases the electron density on the aromatic ring, making it less reactive towards electrophilic substitution. Additionally, the nitrogen can coordinate with the Lewis acid catalysts used in Friedel-Crafts reactions, further inhibiting the reaction. As a result, quinoline is typically unreactive under the conditions of Friedel-Crafts acylation or alkylation.
More basic (a PH of approximately 7.4)
