Question

How to draw isomers?

Answer 1

$<b>$
In the example C4H10, the carbon is the element requiring more bonds, so the row would just have the letter C repeated four times.

Connect each atom in the row from left to right with a single line. The C4H10 example would have a row that looked like C-C-C-C.

Number the atoms from left to right. This will ensure that the correct number of atoms from the molecular formula are used. It will also aid in identifying the structure of the isomer. The C4H10 example would have the C on the left side labeled as 1. The C directly right of it would be 2. The C directly right of 2 would be labeled as 3 and the C on the far right end would be labeled as 4.

Count each line between the drawn atoms as one bond. The C4H10 example would have 3 bonds in the structure C-C-C-C.

Determine if each atom has made the maximum number of bonds according to the notes made from the periodic table of elements. Count the number of bonds that are represented by lines connecting each of the atoms in the row. The C4H10 example uses carbon, which requires four bonds.

Answer 2

In structural isomers, the atoms in each isomer are connected, or bonded, in different ways. As a result, structural isomers often contain different functional groups or patterns of bonding.
