Flashcards in Unit 2: Carbon Properties Deck (25):
1

Branch of science dealing with the element carbon and its many properties.

organic chemistry

2

About 30% of an organism’s dry weight (called Biomass) is ________ in organic molecules.

Carbon

3

About 30% of an organism’s dry weight (called ________) is Carbon in organic molecules.

Biomass

4

The original source for Carbon in all life forms is _______ ________. (CO2 in Photosynthesis)

Carbon dioxide

5

refers to most compounds not containing Carbon.

Inorganic

6

They contain Carbon but are classified as inorganic. (3)

CH4 (Methane gas) and CO2 or CO

7

Carbon has versatility in four directions because of its four __________ _______ in its outer shell.

unpaired electrons

8

These four unpaired electrons allows carbon to act like an ________ in the building of an organic molecule by using those to form covalent bonds with other atoms.

intersection

9

Single Bond between Carbon atoms.(shown as: ______)

C-C

10

Double Bond between Carbon atoms. (shown as:____)

C=C

11

Triple Bond between Carbon atoms. (shown as:_____)

C=C
------

12

Molecules containing mostly Carbon and Hydrogen.

Hydrocarbons

13

Most hydrocarbons are _______ ______. (Some examples are: Fossil fuels, Oils, And Fats)

energy sources

14

The more ________ atoms in a molecule; the more energy there is in the molecule.

Hydrogen

15

___________ are important parts of cell membranes. (The tails of phospholipids)

Hydrocarbons

16

All hydrocarbons are extremely _______ because they are nonpolar molecules. (“Afraid of” water’s polarity.)

hydrophobic

17

(-OH)
This group allows molecules to act as an alcohol or polar molecule.
Name usually ends with “ol”.

Hydroxyls

18

A is at one end of the alphabet. Carbonyl is located on the end of the molecule. (One double bonded oxygen)

Aldehydes

19

K is in the middle of the alphabet.Carbonyl is located in the middle of the molecule. (One double bonded oxygen)

Ketones

20

Functional group with one double bonded oxygen. ((It takes one stroke to make a lower case “n”.)

carbonyls

21

Functional group that has two oxygens…one double bonded and one singled. (It takes two strokes to make an “x”.)
These molecules can act as an acid by losing a Hydrogen atom and can also possibly polar too.

carboxyl

22

Functional group that contains Nitrogen and can act as bases by picking up free H+.

amine

23

Functional group that contains Sulfur.
Sulfur can make Di-Sulfide bridges for “pockets” in protein formation .

Sulfhydrls

24

Functional group that contains Phosphorus.
These molecules are usually involved in E Transfers, such as associated with ATP. It can also act like an Anion, a negative ion.

Phosphate

25

These are the sites of most organic molecules chemical reactions or properties. (They have a function to do.)

Functional groups
