1. CHAPTER 3 REVIEW

2. 3.1 – CARBON COMPOUNDS

3. What is the difference between organic and inorganic compounds?
Organic molecules have lots of C in C-H bonds
Inorganic molecules have lots of C in C-H bonds.
Organic molecules are found only in nonliving things.
There is no difference.

14. How many carbon atoms are in the structural formula shown?1 6 7 8

15. How many hydrogen atoms are in the structural formula shown?3 5 8 12

16. How many hydrogen atoms are in the structural formula shown?
These carbons are not “full” so H atoms are implied!

17. In the structural formula, why is the part outlined in red written as -OCH3 and not -OH3C?
H only have 1 valence electron and can only bond with one other thing
H must always go on the outsides of a molecule
It shows the correct connectivity of the atoms
All of the above
