brilliant! understood very well... thank you
Sir why can't we use the chelation model or Felkin Ahn model for addition to carbonyl group in the last question ?

You can use. Visualizing it this way makes the process shorter.

But, yes using the model is a safer and authentic tool.

ok . thank you sir.
in the first reaction, why Li is not attached to the middle carbon of the substituent OCH2OCH3?
A Sethi

Because that carbon is sp3 hybridized and the hydrogen is not as acidic compared to the other one.
