B) C-F bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
C) C-H bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
D) they are too heavy to reach the stratosphere.
C. C-H bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
