MEDIUMMCQ SINGLEIChO (Chemistry Olympiad)Inorganic Chemistrys- Block 3.0Anomalous Properties of Lithium
Choose the correct statements (s) regarding lithium and alkali metals I. Lithium is much harder. Its m.p and b.p are higher than other alkali metals. II. Lithium is highly reactive and strongest reducing agent in comparison to other group I metal. III. Lithium is deliquescent and crystallizes as hydrates. IV. LiF is comparatively less soluble in water.
A.I, III and IV are correct✓ Correct
B.II and III are correct only
C.I is correct only
D.All are correct
Explanation
Only statement II is incorrect, i.e., lithium is least reactive and strongest reducing agent. This is due to large negative value of standard reduction potential.
