Assertion (A): `CuCI` is more covalent than `NaCI`.
Reason (R ): `Na^(o+)` ion more polarising than `Cu^(o+)` ion.

Assertion (A) : H_2S is more acidic than H_2O . Reason (R) :H-S bond is more polar than H-O bond.

Assertion (A): O_(2) is stronger reducing agent than F_(2) Reason (R ): F_(2) is more electronegative.

Assertion (A): O_(2) is stronger reducing agent than F_(2) Reason (R ): F_(2) is more electronegative.

Assertion (A) : The size of Na^+ ion is less than 'Na' atom. Reason ( R_1 ): Na^+ has more protons than Na atom. Reason ( R_2 ): In general the positive ion (cation) of an element has less size than Its neutral atom.

Mg^(2+) ion more highly hydrated than Na^(+) ion.

Assertion(A) Cu is less reactive than hydrogen. Reason(R) E_(Cu^(2+)//Cu)^(o+) is negative.
