Why Two Necks on a Round Bottom Flask
A single-neck round bottom flask can only accept one fitting at a time, which limits a reaction to either heating under reflux or monitored addition, but not both simultaneously. The angular second neck on this flask adds an independent fitting point — commonly used for a thermometer, addition funnel or nitrogen inlet — while the main neck stays connected to a condenser, all without needing a separate multi-neck adaptor.
