Question

Write bond line formulae 1)3-methyloctane

Answer 1

Explanation:

To draw bond line formula follow these steps:

1. Carbon-carbon bonds are shown by lines drawn in a zig-zag fashion and carbon atoms by line ends and intersection.  
2. singles bond is represented by a single line, a double bond by 2 parallel lines and a triple bond by three parallel lines.  
3. Carbon atoms are not shown but all atoms other than carbon and hydrogen atoms such as oxygen, nitrogen, halogen are shown on zig-zag line.
4. Each carbon on the line end or intersection is attached to required number of hydrogen atoms i.e. terminal denote CH3 group and an unsubstituted intersection denotes a CH2 group.

I have attached a image of the 3-methyloctane bond line formula.

hope it helps and clears your concept.
