Draw the condensed structural formula for urea.

A condensed structural formula is a way of representing a chemical compound that shows the arrangement of atoms and the connectivity between them without depicting all the bonds explicitly. It simplifies the structure by grouping atoms together, making it easier to visualize the molecular composition. For example, in urea, the condensed formula is represented as NH2CONH2, indicating the presence of amine and carbonyl groups.

Urea is an organic compound with the chemical formula CO(NH2)2, commonly known as a waste product formed in the liver from the breakdown of proteins. It plays a crucial role in the nitrogen cycle and is widely used in fertilizers and as a nitrogen source in various chemical processes. Understanding its structure helps in studying its properties and applications in biochemistry and agriculture.

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In urea, the key functional groups are the amine (-NH2) and carbonyl (C=O) groups, which influence its reactivity and interactions with other compounds. Recognizing these groups is essential for predicting the behavior of urea in chemical reactions.
