Question

Highest oxidation state of manganese in fluorides is $+4 (MnF_4)$ but highest oxidation state in oxides is $+7 (Mn_2O_7)$ because

• A. fluorine is more electronegative than oxygen
• B. fluorine does not possess $d$-orbitals
• C. fluorine stabilises lower oxidation state
• D. in covalent compounds, fluorine can form single bond only while oxygen forms double bond

Answer 1

Answer: (D)

in covalent compounds, fluorine can form single bond only while oxygen forms double bond

Answer 2

Oxygen can form $p\pi-p\pi$ bonding while fluorine can form only single bonds.
