Draw the condensed structural or line-angle formula if cyclic, for each of the following: (11.3, 11.5, 11.6)
c. 2,3-dichloro-1-butene

Verified step by step guidance

1. Identify the parent chain: The name '1-butene' indicates a four-carbon chain with a double bond starting at the first carbon.
2. Determine the position of substituents: The '2,3-dichloro' indicates that there are chlorine atoms attached to the second and third carbons of the chain.
3. Draw the carbon backbone: Start with a four-carbon chain, and add a double bond between the first and second carbon atoms.
4. Add the substituents: Attach a chlorine atom to the second and third carbon atoms of the chain.
5. Write the condensed structural formula: Combine the information to write the formula, ensuring the double bond and chlorine atoms are correctly placed.

Key Concepts

Condensed Structural Formula

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 typically groups atoms together to indicate how they are connected, making it easier to visualize the structure of the molecule in a compact form.

Line-Angle Formula

The line-angle formula, also known as the skeletal formula, is a simplified representation of organic molecules where vertices represent carbon atoms and lines represent bonds. This method omits hydrogen atoms attached to carbons, making it easier to visualize complex structures, especially in cyclic compounds, by focusing on the connectivity of the carbon skeleton.

Cyclic Compounds

Cyclic compounds are organic molecules that contain a ring structure formed by the bonding of carbon atoms. These compounds can be saturated or unsaturated, and their properties can differ significantly from their linear counterparts. Understanding the cyclic nature is crucial for accurately drawing their structural representations, such as condensed or line-angle formulas.
