Chapter 17: Problem 66

Draw the structural formula and line drawing for 2 -hexene.

Short Answer

Expert verified

The structural formula for 2-hexene is: H H H H H H | | | | | |_ H-C-C=C-C-C-H Its line drawing or skeletal formula is: CH₃CH2-CH=CH-CH₂CH₃

Step by step solution

Draw the molecular backbone of 2-hexene

Begin by drawing a chain of 6 carbon atoms in a horizontal line. Since there is a double bond between the second and third carbon atoms, draw a double line between them.

Add the hydrogen atoms

To complete the molecular structure, add the hydrogen atoms around each carbon atom so that every carbon atom satisfies the valence requirement, which is 4 bonds for each carbon. In the case of a single-bonded carbon atom, add three hydrogen atoms, and for a double-bonded carbon atom, add two hydrogen atoms. The hydrogen atoms should be connected to the carbon atoms by single bonds. The structural formula for 2-hexene will look like this: H H H H H H | | | | | |_ H-C-C=C-C-C-H

Draw the line drawing (skeletal formula) for 2-hexene

Now, to present 2-hexene as a line drawing (also known as a skeletal formula), we will represent the carbon chain as a zigzag pattern with each vertex being a carbon atom. The double bond between the second and third carbon atoms will be represented by two lines connecting them. In a skeletal formula, we don't need to draw hydrogen atoms as they're implied at each carbon where there is no bond. The line drawing of 2-hexene will look like this: ____ | \ CH₃CH2-CH=CH-CH₂CH₃ This concludes the structural formula and line drawing for 2-hexene.
