To create a model of butane using plastic ball and stick model kit, you will need the following materials:
- 4 small plastic balls (representing carbon atoms)
- 10 short plastic sticks (representing single bonds)
- 2 long plastic sticks (representing double bonds)
- 1 small plastic stick (for labeling)
Here are the steps to create the model:
1. Identify the carbon atoms in butane. In the condensed formula CH3-CH2-CH2-CH3, there are four carbon atoms.
2. Connect the plastic balls to form a chain, representing the carbon backbone of butane. Use three short plastic sticks to join the four plastic balls in a row.
CH3 - CH2 - CH2 - CH3
3. Attach the hydrogen atoms to each of the carbon atoms. Use one short plastic stick to join a hydrogen atom (represented by a small plastic ball) to each of the carbon atoms.

4. This model represents a linear arrangement of butane. However, butane can also have different conformations. To show these conformations, you can rotate the carbon atoms around the single bonds.
5. To show a different conformation, rotate the middle carbon atom (the second carbon atom in the chain) by 60 degrees. Connect the rotated carbon atom to the adjacent carbon atoms with two short plastic sticks.

6. Continue attaching the hydrogen atoms to each carbon atom using short plastic sticks as before.

7. Label the model as "Butane" using a small plastic stick or a sticker.
Note: The model described is a simplified representation of butane, showing only the ball and stick structure. In reality, the bond angles can vary due to the compound's flexibility.
Butane has the condensed formula CH3-CH2-CH2-CH3, use the plastic ball and stick to make a model of butane
