**문제:** 다음 중 위험물의 일반적 개념에 대한 틀린 설명은 무엇일까요?
**선택지:**
1. 반응속도가 급격히 진행된다.
2. 화학적 구조 및 결합력이 불안정하다.
3. **대부분 화학적 구조가 복잡한 고분자 물질이다. (틀린 설명)**
4. 그 자체가 위험하다든가 또는 환경 조건에 따라 쉽게 위험성을 나타내는 물질을 말한다.
**3번 선택지가 틀린 이유:**
**위험물은 화학적 구조가 복잡한 고분자 물질이라는 제한은 없습니다.**
* **간단한 화합물**도 위험물에 속할 수 있습니다.
* 예: **메탄, 에탄올, 황산**
* **위험성은 화학적 구조뿐만 아니라 물질의 물리적 성질, 환경 조건 등 다양한 요인에 의해 결정됩니다.**
