Khaled were in the middle of a
chemistry challenge over the phone. James had
asked Khaled to draw the organic compound

butene, just to test his skills. Khaled, confident
in his abilities, sent back a drawing that looked

spot on: CHEMISTRY chain with a double
carbon-carbon bond.

The two were stumped and decided to go to
their teacher for help.

K CHEMISTRY
To their surprise, their teacher confirmed that
both drawings were correct! The reason was
K CHEMISTRY
that both compounds have the same
molecular formula - four carbon atoms and
K CHEMISTRY
eight hydrogen atoms - and therefore, they
both get the same name: Butene. But here's the
kicker - because they have different structural
formulas, they are actually two different
K CHEMISTRY
compounds, known as isomers. Who knew
chemistry could be so tricky!

K CHEMISTRY
Isomers are molecules that
have the same molecular
K CHEMISTRY
formula but different
K structural formulas.
CHEMISTRY
This can make them tricky to identify, but with a
K CHEMISTRY
little bit of practice, you can become a pro at
spotting isomers. When faced with questions
K CHEMISTRY
about isomers, it's important to carefully
examine the structural formulas and look for
differences in bonding and arrangement of
atoms. By doing so, you can confidently
K CHEMISTRY
determine whether two compounds are isomers
or not. So, don't be intimidated by isomers - with
K CHEMISTRY
a bit of knowledge and practice, you can tackle
any question that comes your way!
