Draw N,N-dimethylethanamide
Draw the skeletal structure of N,N-dimethylethanamide, then check it. The checker compares the molecule you drew with the answer, so a correct structure is accepted however you draw it.
How this exercise works
- Open the exercise in the editor and draw the structure: drag from dot to dot to draw bonds, and tap a bond or an atom to change it.
- Press Check answer. Equivalent drawings are accepted, and a mistake such as a missing carbon or a misplaced group is explained.
- Stuck? Hints reveal the structure step by step, and the worked answer explains the name.
This exercise has 3 hints and a worked answer.
How to read a name like this
The ending -oic acid means a carboxylic acid, COOH, whose carbon is C1 of the chain and counts in the stem. An ester name has two words, the group on the single-bonded oxygen and the acid part ending in -oate; -amide replaces -oic acid for a CONH₂ group and -oyl chloride for a COCl group.
N- in front of a group in an amide name puts that group on the nitrogen. -Carboxylic acid is used when the COOH group is attached to a ring; its carbon is then not counted in the ring.
Each of these groups contains a C=O. Draw it on the carbon of the group (C1 of a chain), then add the O, N or Cl that the group carries.
Rules this name uses
- Di-, tri- and tetra- mean two, three or four of the same group or bond, and each of them has its own locant, even when two groups are on the same carbon. Multipliers do not count in alphabetical order.
- N- means that the group after it is bonded to the nitrogen, not to a carbon; N,N- puts two groups on the nitrogen.
