Skeletal structural formulas of pentane,2 methyl butane and 2,2 dimethyl propane
To draw the skeletal structural formulas of pentane, 2-methyl butane, and 2,2-dimethyl propane, follow these steps:
1. Understand the rules:
- Each line segment represents a carbon-carbon bond.
- Each endpoint and line intersection represents a carbon atom.
- Hydrogen atoms bonded to the carbon atoms are not shown explicitly, but can be inferred.
2. Start with pentane:
Pentane has 5 carbon atoms in a straight chain. Draw five line segments connected together in a row.
CH3 - CH2 - CH2 - CH2 - CH3
3. Moving on to 2-methyl butane:
2-methyl butane has 4 carbon atoms in a chain with a branch of one carbon atom attached. Start with the chain of four carbon atoms, and then add the branch.

4. Lastly, draw the structure of 2,2-dimethyl propane:
2,2-dimethyl propane has a main chain of three carbon atoms with two branches of one carbon atom each. Start with the chain of three carbon atoms and draw two branches.

Following these steps, you should be able to draw the skeletal structural formulas for pentane, 2-methyl butane, and 2,2-dimethyl propane.
Sure! Below are the step-by-step instructions for drawing the skeletal structural formulas of pentane, 2-methyl butane, and 2,2-dimethyl propane.
1. Pentane: The molecular formula of pentane is C5H12.
- Start by drawing a straight line to represent the carbon backbone of pentane.
CH3 - CH2 - CH2 - CH2 - CH3
- Attach one carbon atom (CH3 group) to the first carbon in the chain and another carbon atom (CH3 group) to the last carbon.
CH3 - CH2 - CH2 - CH2 - CH3

2. 2-Methyl Butane: The molecular formula of 2-methyl butane is C5H12.
- Begin by drawing a straight line to represent the carbon backbone of butane.
CH3 - CH2 - CH2 - CH2 - CH3
- Attach one carbon atom (CH3 group) to the second carbon in the chain.
CH3 - CH(CH3) - CH2 - CH2 - CH3
3. 2,2-Dimethyl Propane: The molecular formula of 2,2-dimethyl propane is C5H12.
- Start by drawing a central carbon atom with three other carbon atoms attached to it, forming a tetrahedral shape.
