" (i) "[" Assertion : Positive ions will be wider than parent atoms."],[" Reason : Nuclear charge attracts them closer."]

Assertion : Aniline is better nucleophile than aniline ion. Reason : Aniline ion have +ve charge.

Assertion : Aniline is better nucleophile than anilium ion. Reason : Anilium ion have +ve charge.

Assertion: Radius of the ion is always smaller than the parent atom. Reason: Ion is formed by the loss or gain of electrons by the parent atom.

Assertion : Size of an anion is larger than their parent atom. Reason : Z_(eff) of anion is greater than that of their parent atom.

Assertion: Nuclear density is greater than atomic density. Reason: Nuclear size (volume) is greater than atomic size.
