Why are the products of Grignard reaction on an alpha-chiral ketone diastereomers rather than a racemate?

First of all, welcome to ChemSE on your first post. Allow me to expand on the Comment of Karsten Theis and provide you with an illustration. If a compound is racemic and bears a single stereocenter, ...

Why are the products of Grignard reaction on an alpha-chiral ketone diastereomers rather than a racemate?

The reaction introduces a new chiral center into your mix, that chiral carbon being the one that has the tertiary alcohol on it (let’s call this #2). The product will produce a mixture of those chiral ...

How to depict small molecules such as D-glucose based on isomeric SMILES

Wikipedia link states: Configuration at tetrahedral carbon is specified by @ or @@. Consider the four bonds in the order in which they appear, left to right, in the SMILES form. Looking toward the ...

Is this formula for number of optical isomers correct?

I think that the enantiomeric pairs 1 and 4; 2 and 3 are identical. Just rotate the molecule by 180 degrees about an axis perpendicular and passing through the centre of CH3 - CH3 line. This counting ...
