Q79 / 180 · NEET 2018 · Chemistry

Which of the following statements is not true for halogens?

Correct answer
A
All but fluorine shows positive oxidation states.
B
All are oxidizing agents.
C
All form monobasic oxyacids.
D
Chlorine has the highest electron-gain enthalpy.

Solution

Fluorine can show only negative oxidation state $(- 1)$ because it has the highest electronegativity among all elements.

Hence, the correct answer is option: 'A'.
