Drawing chemical structures
Remember:
Molecular Formula
Structural Formula
C2H4O2
Condensed Formula
CH3COOH
Part 1: For each condensed structure, convert it to a line-angle structure.
1. CH3CH(OH)CH(CH3)C2H5
2. CH3CHClCHClCOCH2CN
3. CH3CH2CO2CH(C2H5)2
4. CH3(CH2)2CH(CH3)COOH
5. (CH3)2NCH2CH=CH2
6. (CH3)2CHCHBrCH2CH3
7. (CH3)3CCH2CH(CH3)C2H5
8. (C2H5)2C=CHCHO
Line-Angle (Skeletal)
Part 2: For each line-angle structure, convert it to a structural formula.

This is alanine, an amino acid that is used to build proteins in your body. Do you remember what the
wedge and dash marks mean? The wedge means that the –CH3 group (methyl group) is coming towards
you and the –H is going away from you. We will be using this notation throughout the year.
