การทดสอบเรื่องสารประกอบไฮโดรคาร์บอนที่มีหมู่ฟังก์ชัน

The given compound CH3NH2 is methylamine, which is an example of an amine. Amines are organic compounds that contain a nitrogen atom bonded to one or more carbon atoms. They are characterized by the presence of the functional group -NH2. Methylamine specifically has a methyl group (-CH3) attached to the nitrogen atom. Therefore, the correct answer is "เอมีน" (methylamine).

The given chemical formula C2H5OH represents ethanol, which is commonly known as alcohol. Alcohol is classified as a type of organic compound called alcohols. Therefore, the correct answer is "แอลกอฮอล์" (alcohol).

The correct answer is "ไฮดรอกซิล" because the functional group -OH is called a hydroxyl group, and "ไฮดรอกซิล" is the Thai translation for hydroxyl.

The correct answer is "แอลดีไฮด์" because it is the only compound among the given options that matches the formula "HCHO", which stands for formaldehyde. Formaldehyde is an organic compound that is commonly used as a disinfectant and preservative. It is also a key ingredient in the production of resins and plastics.

The given compound CH3CONH2 is an amide. This is because it contains a carbonyl group (C=O) bonded to a nitrogen atom (N), which is characteristic of amides. The presence of the methyl group (CH3) attached to the carbonyl carbon further confirms that it is an amide.

The given chemical formula, CH3COOH, represents acetic acid, which is an organic acid. Organic acids are characterized by the presence of a carboxyl group (COOH) in their structure. Acetic acid is commonly found in vinegar and has a sour taste. Therefore, the correct answer is "organic acid."

The correct answer is "คาร์บอกซิล" because the functional group -COOH is called a carboxyl group, and "คาร์บอกซิล" is the Thai translation for carboxyl.

The given compound, CH3COOCH3, is an ester. Esters are organic compounds that are formed when an alcohol reacts with an acid, resulting in the elimination of water. In this case, the compound is formed by the reaction between acetic acid (CH3COOH) and methanol (CH3OH), resulting in the formation of methyl acetate (CH3COOCH3). Esters are characterized by the presence of a carbonyl group (C=O) bonded to an oxygen atom, which is then bonded to an alkyl group.

The given chemical formula CH3COCH3 represents acetone, which is a type of ketone. Ketones are organic compounds that contain a carbonyl group (C=O) bonded to two alkyl or aryl groups. Acetone, also known as propanone, is a common ketone that is a colorless, volatile liquid with a characteristic odor. It is widely used as a solvent and in the production of various chemicals and consumer products. Therefore, the correct answer is "ketone".

The given chemical formula CH3OCH3 represents the compound ethyl ether. Ethyl ether is a type of organic compound known as an ether, which is characterized by the presence of an oxygen atom bonded to two alkyl or aryl groups. In this case, the two alkyl groups are methyl groups (CH3), hence the name ethyl ether.
