Question

What are the pi and sign a bonds in a molecule of lidocaine? Are there any delocalized pi bonds if so label them? And is the molecule chiral if so add an * lecture to the strerocenters

Answer 1

lidocaine is used as local anesthetic

Except the 3 double bonds in benzene rings and one bond between the carbonyl group

(bond between carbon and oxygen) all the other bonds are sigma bonds In lidocaine

molecule.

The pi bonds that are present in the benzene ring are delocalized pi bonds (red colored)

A molecule is said to be chiral if it has atleast on chiral carbon and without any elements Of

symmetry. A chiral carbon should attach to four different atoms or groups. Since there is

no chiral carbons present In lidocaine it IS not a chiral molecule.
