# What is the name of this compound? [closed]

This doesn't look like an amide. What is its IUPAC name? Is this compound even possible?

• Without hydrogen at nitrogen, as you draw, uncharged – likely impossible. – mykhal Jun 12 at 8:33
• Is it a homework? Just asking. – mykhal Jun 12 at 9:05
• No .I asked it to one of my teachers, he said it is impossible to solve! I made up this question. – compenthusiast Jun 12 at 11:09
• Just assume that hydrogen to be there. – compenthusiast Jun 12 at 11:11

You likely mean $$\ce{CH3-CO-NH-CO-CH2CH3}$$.
$$\ce{R-CO-NH-CO-R}$$ compounds are called imides (in contrast to amides $$\ce{R-CO-NH2}$$, like in inorganic chemistry, $$\ce{M^INH2}$$ vs $$\ce{M_{2}^{I}NH}$$). They can also be „intramolecular“, i.e. cyclic (look at succinimide or phthalimide).
A similar symmetric compound $$\ce{(CH3CO)2NH}$$diacetamide“ exists and can be bought (melting point 79 °C). Its current preferred name is N-acetylacetamide.
