Draw the E2 elimination product of the reaction. Take into account that the starting stereochemistry affects the resulting double bond stereochemistry.
• Consider E/Z stereochemistry of alkenes.
• Do not show stereochemistry in other cases.
• You do not have to explicitly draw H atoms.
• In cases where there is more than one answer, just draw one.
