1. Building Organic molecules #1
The black beads are Carbon – all 4 holes must be filled
The white small beads are hydrogens – they only bond in one place and are used to fill the empty bonds of carbon

2. Follow these directions
The first slide will give you the name of what you are to build and maybe a hint.
The answer is on the next slide.
Do not look ahead until you have built the model
This is what your test will be like on the 12/13. Working with a partner, building models. If you just flip though the powerpoint and do not build the models you are only making the test harder for yourselves.

3. 1. Pentane
Use the long sticks between the carbons and the short sticks between
the hydrogens and carbons.

4. Pentane has 5 carbons with 3 hydrogen atoms on each side and two hydrogen atoms on each of the three in the middle

5. 2) 1-hexene
Hint - Use the springs for the double bond

6. 1-hexene has 6 carbon atoms with a double bond after the first carbon
1-hexene has 6 carbon atoms with a double bond after the first carbon. The springs will push away from each other and form 2 arches.

7. 3) 2-methyl butane

8. Butane is a 4 carbon chain – methyl is a one carbon branch off the 2nd carbon. Be sure the number and placement of hydrogen atoms is correct

9. 4) 4-methyl-2-pentyne
Remember to use springs for the multiple bonds

10. Remember it is 3 dimensional and can be flipped one way or the other
Remember it is 3 dimensional and can be flipped one way or the other. Always number in one direction with the double or triple bond being the lowest number. C 3 5 4 2 1

11. 5) Cis-2-butene

12. Cis means the same- the carbons should be on the same side after the double bond. But = 4 carbons with the double bond after the second bond.

13. 6) cyclohexane

14. Cyclo- is a prefix for circle hex- is six carbons and ane- is all single bonds

15. 7) 2,2 –dimethyl butane

17. Trans 2,3 dichloro 2 - butene
The green beads are chlorine
Trans 2,3 dichloro 2 - butene
