Question

Match Column-I with Column-II and select the correct answer by the given codes.

Column I (Atoms)		Column II (Properties)
A	$He$	p	Highly electronegative
B	$F$	q	Most electropositive
C	$Rb$	r	Strongest reducing agent
D	$Li$	s	Highest ionisation energy

• A. A - (s), B - (q), C - (r), D - (p)
• B. A - (p), B - (s), C - (q), D - (r)
• C. A - (s), B - (p), C - (r), D - (q)
• D. A - (s), B - (p), C - (q), D - (r)

Answer 1

Answer: (D)

Helium (He) $1s^2$ $\to$ Highest ionisation energy due to noble gas in nature.
Fluorine(F) $1s^2,2s^{2}2p^3\to$ High electronegativity in nature due to small size and -1 oxidation state.
Rubidium(Rb)$\to$ Most electropositive element due to large atomic size.
Lithium(Li)$\to$ Strongest reducingagent due to greaterhydration energy.
