Description

"Organic Compounds and Organic Synthetic Materials" PPT (Lesson 1)

Part One: Teaching Objectives

1. Can distinguish between inorganic substances and organic substances

2. Know the properties and uses of some simple organic compounds.

Organic matter and organic synthetic materials PPT, part 2: simple organic matter

There are tens of millions of substances in nature, the vast majority of which are organic matter.

(1) Sources of organic matter

Organic matter in nature evolved from inorganic matter.

With organic matter, there is life, and ultimately there is human beings.

(2) What are organic matter

Organic matter is a class of compounds containing ____.

Most contain elements such as ____, ____, ____, ____ etc.

(Except carbon oxides, carbonic acid, carbonates, etc.)

Although the above are carbon-containing compounds, they are similar to inorganic compounds in structure, composition, and properties.

(3) Simple organic matter

1. Methane

(1) Composition CH4

A methane molecule is made up of 1 carbon atom and 4 hydrogen atoms

(2) Existence

Biogas, natural gas, etc.

The main component is methane

(3) Purpose

Commonly used as fuel for heating

(4) Nature

flammable

Ignite methane gas, place a beaker with an inner wall dipped in clarified lime water over the flame, and observe what experimental phenomena occur?

Purity verification method:

Take a small amount of pure gas to be tested and put it into a test tube. Seal the mouth of the test tube with your thumb. Place the mouth of the test tube close to the flame of the alcohol lamp. Release your thumb. If you hear a sharp popping sound, it means the gas is impure.

Organic matter and organic synthetic materials PPT, Part 3: Classroom exercises

1. Which of the following substances are organic matter----( )

A. CO B. H2CO3

C. C2H2 D. H2O2

2. The simplest organic matter is ---- ( )

A. C2H2 B.CH4 C.CH2O D. CO2

3. On May 27, 2012, my country’s “Yangyang 6” scientific research vessel set sail to conduct an “accurate survey” of combustible ice resources in the northern area of ​​the South China Sea. Combustible ice is an icy substance formed from water and natural gas under high pressure and low temperature conditions. Its chemical formula is ( )

A． CO2 B. H2O

C. CH4 D. CH4·xH2O
