Parts and what they mean
- Structure I: neutral phenol (one Kekulé ring) (संरचना I: उदासीन फ़ीनॉल (एक केकुले वलय)) — neutral phenol (one Kekulé ring)
- Structure II: O⁺ (C=O⁺–H) and negative charge on an ortho carbon (संरचना II: O⁺ (C=O⁺–H) और ऋण आवेश एक ऑर्थो कार्बन पर) — O⁺ (C=O⁺–H) and negative charge on an ortho carbon
- Structure III: O⁺ and negative charge on the para carbon (संरचना III: O⁺ और ऋण आवेश पैरा कार्बन पर) — O⁺ and negative charge on the para carbon
- Structure IV: O⁺ and negative charge on the other ortho carbon (संरचना IV: O⁺ और ऋण आवेश दूसरे ऑर्थो कार्बन पर) — O⁺ and negative charge on the other ortho carbon
- Structure V: neutral phenol (other Kekulé ring) (संरचना V: उदासीन फ़ीनॉल (दूसरा केकुले वलय)) — neutral phenol (other Kekulé ring)
- Curved arrows (वक्र तीर) — The O lone pair is pushed into the ring: oxygen becomes positive, which makes the O–H bond more polar.
- Charge separation in phenol (फ़ीनॉल में आवेश पृथक्करण) — Structures with separated charges contribute less; phenol is less stabilised than phenoxide.
