For instance, the amide derived from acetic acid is named acetamide (CH 3 CONH 2). IUPAC recommends ethanamide, but this and related formal names are rarely encountered. When the amide is derived from a primary or secondary amine, the substituents on nitrogen are indicated first in the name.

2016年4月9日 · Three types of amide - 1° 2° and 3°. -CONH2 is 1° amide, in the image it is 2° amide. If you take out that one hydrogen too you will get a 3° amide. Amides are derivative of carboxylic acids. It consists of 2 parts, and the bond between carbonyl carbon and nitrogen of ammonia is called is amide bond.

Primary amides are amides in which the nitrogen atom is bonded to one hydrogen atom and two carbon atoms. The general formula for primary amides is RCONH 2, where R represents an alkyl or aryl group. Primary amides are often considered the simplest and …

2022年9月12日 · An amide functional group consists of a carbonyl group bonded to a nitrogen. In simple amides, two hydrogen atoms are bonded to the nitrogen (-CONH2) while in more complex amides, the nitrogen is bonded to one or two aliphatic or aromatic groups (-CONR).

2022年9月15日 · Identify the general structure for an amide. Identify the functional group for an amide. Names amides with common names. Name amides according to the IUPAC system. The amide functional group has an nitrogen atom attached to a carbonyl carbon atom.

酰胺可以看作是 含氧酸 R n E (=O) x OH的 羟基 被 氨基 （或 胺）所取代而产生的衍生物。 一些重要的酰胺化合物有： 碳酰胺，E为 碳 时，具RC (=O)NR 2 结构的酰胺，也是最主要的酰胺（在没有注明的情况下，酰胺一般都指羧酸的氨基衍生物）化合物。 磷酰胺，E为 磷 时，具R 2 P (=O)NR 2 结构的酰胺。 磺酰胺，E为 硫 时，具RS (=O) 2 NR 2 结构的酰胺。 涉及酰胺结构的重要化合物有： 二酰胺，二元羧酸的衍生物，如 草酰胺 、 邻苯二甲酰亚胺。 内酰胺，由酰胺 …

2024年8月15日 · 酰胺基，包括r和h（同碳氢），其结构式有多种表现：-conh2、-conhr、-conr2。具体如乙酰胺，其氨基去氢后的结构式为ch3conh-。

选择画单间工具，双击苄位，输入conh2，点选择框，就解决了

2023年11月21日 · The amide functional group is given as -CONH2. What is an amide vs Amine? An amide differs from an amine in both its structure and properties. An amide consists of an acyl group attached to the...

2024年4月30日 · 氰基（-CN）在水解反应中，会加水分子的氢原子形成羟基（-OH），同时氰基的碳原子与氧原子形成双键，生成酰氨基（-CONH2）。这个过程称为水解，反应的化学方程式可以表示为： \[ \text{-CN + H}_2\text{O} \rightarrow \text{-CONH}_2 + \text{H}^+ \]
