Which sample is physostigmine?
|
|
|
|
Sorry. Sample A’s melting point doesn’t match physostigmine’s melting point.
|
|
|
|
Sorry. Sample B’s melting point doesn’t match physostigmine’s melting point.
|
|
|
|
Possibly. But is sample C the only one with the same melting point as physostigmine?
|
|
|
|
Sorry. Sample D’s melting point doesn’t match physostigmine’s melting point.
|
|
|
|
Possibly. But is sample E the only one with the same melting point as physostigmine?
|
|
|
|
Sorry. Are you sure no samples have the same melting temperature as physostigmine?
|
|
|
|
Correct! Since both Sample C and Sample E have the same melting point as physostigmine, we can’t tell which one is physostigmine.
