📝 Detailed explanation

Mentol — to'yingan halqali spirt, C₁₀H₂₀O.
σ bog'lar soni: barcha C–C, C–H, C–O, O–H bog'lari.
C–H bog'lar: 20 ta (har bir H bilan).
C–C bog'lar: halqada 6 + tashqarida (izopropil va metil) — to'plam: halqa 6 + (5 ta tashqi C: 1 metil + 3 izopropil C, izopropil ichidagi 2 ta + metilning halqaga ulanishi 1 ta) → C–C jami 9 ta.
C–O bog': 1 ta.
O–H bog': 1 ta.
Jami σ bog': 20 + 9 + 1 + 1 = 31.
Javob: 31.
