Magazine Chapter 2: Q36E (page 128)
Use the build a molecule simulation (http://openstaxcollege.org/1/16molbuilding) to repeat Exercise 2.34, but build a molecule with three carbons, seven hydrogens, and one chlorine.
- Draw the structural formula of this molecule and state its name.
- Can u arrange these atoms to make a different molecule? If so, draw its structural formula and state its name.
- How are molecules drawn in (a) and (b) the same? How do they differs? What are they called (the type of relationship between these molecules, not their names)?
Short Answer
(a) Structural formula:
\(\)
Name- \(1 - chloropropane\)
b.
Name- 2- Chloropropane
c. Molecular formula is same, structure is different, structural isomers.
Step by step solution
write its molecular formula
(a.) So, the formula is C3H7Cl
(b) Name- 2- Chloropropane
(c) Molecular formula is same, structure is different, structural isomers.
: Draw the structural formula according to molecular formula
: write name according to structure
In propane Cl is attached at 1st carbon So, the name of compound is
1-Chloropropane
Step 4: part b. Change the place of Cl from 1st carbon to 2nd carbon.
Step 5: Write the name of molecule according to structure
Name of new molecule is 2-Chloropropane
Step 6: Compare both the structures to find the relation between them
In both a and b the molecular formula is same it means the no. of carbon and no. of hydrogen and no. of Chlorine are same.
Bothhave different structure of molecule because chlorine is connected at the first carbon in first part. Meanwhile, in second part the chlorine is connect at 2nd carbon.
So, the relation between these molecules 鈥� We know that those molecules which have same molecular formula but different structure called structural isomers.
