My teacher did like this forming a really unstable cyclopropyl group but this is the correct answer instead. My question is why the product will be even formed? In the mechanism that my teacher had drawn he formed a really unstable carbo anion there whereas he could have formed a primary carbanion and next may it have formed a four membered ring.
Why did not the neucleophile (acetic acid) did not approach to the carbon atom with which the chlorine is attached directly? Forming
And this next form a very stable cyclo propyl carbocation. (Which is one of the most stable carbocations) So which explaination should I rely on? Thank you.
