OE1 and E2 are not likely because there are no ẞ-hydrogen atoms. SN1 and E1 are not possible because the leaving group is poor. An SN2 reaction is ruled out because the substrate is primary. An E2 reaction is possible because the attacking species is a strong base. O SN1 and E1 are unlikely because the attacking species is not a weak base or weak nucleophile.

Consider the reaction scheme shown below. Apply the steps outlined in Parts 1
and 2 to decide which mechanism operates in this case.
&
Br
Choose one or more:
O Competition is feasible.
OE1 and E2 are not likely because there are no ẞ-hydrogen
atoms.
✓ SN1 and E1 are not possible because the leaving group is
poor.
An SN2 reaction is ruled out because the substrate is
primary.
O An E2 reaction is possible because the attacking species is a
strong base.
O SN1 and E1 are unlikely because the attacking species is not
a weak base or weak nucleophile.
