Parts and what they mean

• n-Butane — 273 K (n-ब्यूटेन — 273 K) — Non-polar: only weak van der Waals forces, so the lowest b.p.
• Methoxyethane — 281 K (मेथॉक्सीएथेन — 281 K) — An ether is only weakly polar.
• Propanal — 322 K (प्रोपेनैल — 322 K) — Dipole–dipole attraction between polar C=O groups (weak molecular association).
• Acetone — 329 K (ऐसीटोन — 329 K) — Also dipole–dipole; ketones are slightly more polar than aldehydes of similar size.
• Propan-1-ol — 370 K (प्रोपेन-1-ऑल — 370 K) — Intermolecular hydrogen bonding — absent in aldehydes and ketones — gives the highest b.p.
• Boiling point in kelvin (क्वथनांक केल्विन में) — NCERT values (Section 8.3).
