无机推断题学科特点明显,它是以元素化合物知识为主,集基本概念和基本理论为一体的综合性题目。它符合高考命题由知识型向能力型转变的趋势,具有很高的区分度和很好的选拔功能,是高考命题的必考题型。根据教学大纲和考试大纲的要求,我们在复习时必须掌握以下问题。一、试题地位无机推断题不仅能考查学生在中学阶段所学的元素的单质及其化合物以及物质结构、元素周期律、电解质溶液、氧化还原反应、化学用语等知识的掌握情况,而且能考查学生掌握基础知识的熟练程度和灵活运用知识进行逻辑推理的综合能力。无机推断题可分为以“构”、“位”、“性”为基础的元素所在周期表中位置的推断和以元素化合物为基础的无机框图推 Inorganic deduction subject features obvious, it is based on the knowledge of elemental compounds, set the basic concepts and basic theory as one of the comprehensive topic. It is consistent with the college entrance examination proposition from knowledge-based to ability to change the trend, with a high degree of distinction and a good selection function, the college entrance examination will be the subject of exam questions. According to the syllabus and exam outline requirements, we must master the following questions in the review. First, the test position Inference questions can not only examine the students learn in the secondary phase elemental elements and their chemical composition and substance structure, the periodic law of the electrolyte solution, redox reaction, chemical terms and other knowledge mastery, but also to examine the students Master the proficiency of basic knowledge and flexible use of knowledge for logical reasoning comprehensive ability. Inorganic inference problems can be divided into “structure ”, “bit ”, “sex ” based on the elements of the periodic table inferred and based on elemental compound based inorganic block diagram push
