MHT CET 2023 Chemistry question

Not in JEE Main or NEET syllabus

Which among the following statements of group -1 elements is NOT true?

(A)Unipositive ions have inert gas configuration
(B)Compounds of unipositive ions are paramagneticCorrect
(C)These form colourless in +1 state
(D)These have high negative values of standard reduction potential

Answer: (B)

Solution

Alkali metals form ions with noble-gas configuration (a, true). Because there are no unpaired electrons, ions and their compounds are diamagnetic, not paramagnetic, so statement (b) is false. Their ions have no d-d
