In a reflux setup, where is the condenser typically attached?

Explanation:
In a reflux setup, the condenser is placed at the top of the flask where vapors naturally rise. Mounting the condenser on the neck allows the hot vapors to immediately encounter the cool surface, condense back into liquid, and drip back into the reaction mixture. This design keeps the system at the boiling temperature without losing material, enabling continuous cycling during reflux. If the condenser were placed in the middle, along the side, or at the bottom, it wouldn’t intercept the rising vapors effectively, which would reduce condensation, risk loss of material, or disrupt heating and stirring.
