What is the driving force for the reaction

F₂ + H₂O -> H₂F₂ + O₂

Is the very low bond energy of F₂?

Joshi sir comment

Considering the electrode potential of hydrogen to be zero, electrode potential of fluorine is +2.87 volt. It implies that fluorine is best oxidising agent, and thus it oxidises oxygen in the given reaction. Besides it low bond energy of fluorine is also a factor for its dissociation and participation in the reaction.

Amount of DCl = 4 milimole

Amount of NaOD = 8 milimole

After reaction of acid and base 

Amount of NaOD remaining = 4 milimole

Total volume = 100 ml = 0.1 lit

so [OD] =4*10-3/0.1=4*10-2 (1) Given pD = 13.6 so log[D+] =-13.6= 14¯.4 [D+] =2.5*10-14 (2) Now solve

It is syn reagent

It is m-CPBA

mCPBA is a good oxidizing agent for alkenes and ketones. Here both are present, in that case mCPBA attacks on alkene. Alkene on OMe side is more reactive. So make epoxide this side. Remember also that stereo nature is not changed in this reaction means cis be cis and trans be trans. 

Does stabilization of a charge mean willingness of other atoms in the molecule to share the charge or the extent of sharing of charge ? If its the 1st then how does that stabilize the charge?

Sharing is the case applicable for the atoms of same electronegativity, thus by sharing electrons (charges) atoms make their orbital configurations stable according to the rules defined for stability.

Is the H on B-carbon sterically hindered ?

Joshi sir comment

Steric hindrance is a relative word, so is compared between two carbons.

Tertiary carbon is always more sterically hindered than primary,

so β carbon is more hindered than α in this compound
