DefineAnswer:
the term constitutional isomer.
1. O
2. Two
Your lone pairs
Answer:
3. Two unpaired electrons
Constitutional isomers are compounds with the same molecular formulas
4. two bonds
but different structural formulas.
Answer:
Two (or more) different chemical compounds with the same
molecular formula but different connectivity between the
atoms in their structural formulae.
Question 4 pts
Explain (using specific evidence) what makes the following two compounds
constitutional isomers of one another:
Your Answer:
Both compounds are , but they are arranged differently and have
different connectivity.
