Найдите сумму степеней окисления атомов углерода в гуанине.

  1. +11
  2. +12
  3. +13
  4. +10

📝 Detailed explanation

Известные степени окисления:H = +1
O = −2
N = −3
Для нейтральной молекулы сумма степеней окисления равна нулю:
x + 5(+1) + 5(−3) + (−2) = 0
x + 5 − 15 − 2 = 0
x − 12 = 0
x = +12
