(a)
Interpretation:
The stronger nucleophile has to be selected from the given set of nucleophiles.
Concept Introduction:
Nucleophile:
The species, that make a covalent bond by donates a pair of electrons is known as nucleophile.
Stronger nucleophiles are negative charge or ready to donate a pair of electrons.
Weak nucleophiles are neutral molecules with lone pair of electrons.

- Given that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination. The alkyl halides in (a) and (b) are diastereomers of each other. How are the products of these two reactions related? Recall from Section 3.2A that C6H5 −is a phenyl group, a benzene ring bonded to another group.arrow_forwardGiven that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination.
