Are C2H2F2 and H2O2 polar or nonpolar?

Are C2H2F2 (1,1-difluoroethene) and H2O2 (hydrogen peroxide) polar or nonpolar molecules? Could you please explain the factors that contribute to their polarity, including molecular structure and electronegativity differences?

flourine substituted ethelyne

cis isomer

c-f bonds are much more polar than c-h bonds

both c and f bonds on same side molecule is polar

trans isomer

both c-f bonds on opposite side

molecule is not polar

as far as Alkaline hydrogen peroxide non polar

In aqueous solution, hydrogen peroxide can oxidize or reduce a variety of inorganic ions. When it acts as a reducing agent, oxygen gas is also produced. In acid solution Fe2+ is oxidized to Fe3+,

[2 Fe2+] + H2O2 + 2 H+(aq) → 2 [Fe3+] + 2H2O(l)

and sulfite (SO32−) is oxidized to sulfate (SO42−). However, potassium permanganate is reduced to Mn2+ by acidic H2O2. Under alkaline conditions, however, some of these reactions reverse; for example, Mn2+ is oxidized to Mn4+ (as MnO2).

Another example of hydrogen peroxide acting as a reducing agent is the reaction with Sodium hypochlorite, this is a convenient method for preparing oxygen in the laboratory.

NaOCl + H2O2 → O2 + NaCl + H2O

Hydrogen peroxide is frequently used as an oxidizing agent in organic chemistry. One application is for the oxidation of thioethers to sulfoxides.[citation needed] For example, methyl phenyl sulfide was oxidised to methyl phenyl sulfoxide in 99% yield in methanol in 18 hours (or 20 minutes using a TiCl3 catalyst):

Ph-S-CH3 + H2O2 → Ph-S(O)-CH3 + H2O

Alkaline hydrogen peroxide is used for epoxidation of electron-deficient alkenes such as acrylic acids, and also for oxidation of alkylboranes to alcohols, the second step of hydroboration-oxidation.
