Chemistry
1 answer:

Answer:

ethyl 3-ethoxy-3-hydroxy-2-isopropyl-5-methyl hexanoate

Explanation:

In this case, we have a <u>very strong base</u> (sodium ethoxide). Therefore, this compound will remove a hydrogen from ethyl 3-methyl butanoate generating a <u>carbanion</u>.

This carbanion, can attack <u>another ethyl 3-methyl butanoate molecule </u>on the carbonyl group generating a new C-C bond and producing a negative charge in the oxygen.

Then the ethanol can <u>protonate</u> the molecule generating an "OH" group and the ethoxide.

See figure 1

I hope it helps!
