The protons of methylene group between the two carbonyl groups in ethylacetoacetate are acidic in nature. When compounds containing such acidic protons are treated with bases the loose proton and form enolates.
In this particular example when ethylacetoacetate is reacted with methyl magnesium bromide, the methyl group abstracts the acidic proton and converts into
methane gas. The enolate when hydrolyzed is again converted into ethylacetoacetate as shown below,
Answer: New concentration of
is 0.23 M.
Explanation:
The given data is as follows.
Moles of
= 0.06 mol
Moles of
= 0.08 mol
Therefore, moles of
added are as follows.
Moles of
= 
= 0.003125 mol
Now, new moles of
= 0.06 + 0.003125
= 0.063125
Therefore, new concentration of
will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of
is 0.23 M.
