Draw the products of the following acid/base reactions, depict the proton exchange with electron-pushing arrows, AND circle the proper reaction arrow to indicate if reactants or products (or neither) are favoured at equilibrium. Using the provided pKa table, write all relevant pKa values (i.e. for the two reactants if available and the conjugate acid). Finally, label the acid, base, conjugate acid, and conjugate base.

I’m so confused please help

The four bonds of carbon tetrachloride (CCl4) are polar, butthe molecule is nonpolar because the bond polarity is canceledby the symmetric tetrahedral shape. When other atoms substitutefor some of the Cl atoms, the symmetry is broken and the mol-ecule becomes polar. Use Figure to rank the fol-lowing molecules from the least polar to the most polar: CH₂Br₂,CF₂Cl₂, CH₂F₂, CH₂Cl₂, CBr₄, CF₂Br
