organic chem multiple choice help The hydrogen marked "A" is Dependence of nucleophilicity on the atom's electro negativity Dependence of basicity on the atom's electro negativity Dependence of nucleophilicity on the atom's size Dependence of basicity on the atom's size Dependence of nucleophilicity on the scribe hindrance concept The following reaction equilibrium is shifted to the left. What does this is peri mental result tell you about participating compound? Thiols are stronger nucleophiles , than Thiolatcs are stronger nucleophiles, than alkoxides Thiols are weaker nucleophiles, than alcohols Which type of reaction has shown on the following scheme?

Explanation / Answer

13) Dependance of basicity on atom's electronegativity

Here, oxygen is more electronegative than carbon so hydrogen attached to oxygen will be more acidic

14) Thiols are more acidic than alcohol so the equilibrium will shift towards left

So thiols have more pKa as they have high Ka .

15) This is bimolecular elimination

As base will deprotonate the molecule with simultaneous removal of halide ion .

The reaction is bimolecular so it is known as E2
