C-C-C-C | C

It looks like you are drawing a molecular structure using lines to represent bonds and the letter "C" to represent carbon atoms. The structure resembles a carbon chain, possibly indicating a branched alkane. Here’s a breakdown of what you seem to have drawn:

C-C-C-C
      |
      C

In this structure:

• There are four carbon atoms in a straight chain (C-C-C-C).
• The fourth carbon has a branch (denoted by the line and the additional "C" below), suggesting that one of the carbons is connected to another carbon.

This would represent 2-methylbutane or potentially a different isomer depending on how the branches are structured. If you have specific questions about the molecule, its properties, or what you need to study in relation to it, feel free to ask!
