The amazing world of biomolecules
Question:
What is known as the medium of life?
Answer:
water- this is because it is found inside and outside of the cells of the huma
body
example: RBC consist of water and the blood is also made up of water
Question:
Is water polar or nonpolar? Why is this property helpful?
Answer:
polar- this allows water to dissolve many polar solutes
,Question:
What is organic chemistry?
Answer:
the study of (the chemical and physical properties of) molecules containing
carbon
Question:
Why is carbon considered the superglue of biomolecules?
Answer:
1. It has 4 valence electron which allows it to make seperate bonds
2. Carbon can form bond with many other molecules
3. Carbon can form long chains of carbon molecules (called a polymer)
4. Carbon can form double and triple bonds with itself and some other
molecules
5. Carbon can form cyclic molecules which are very stable
,Question:
What are alkanes? what is the general chemical formula?
Answer:
these are straight single bond chains of carbon. the general formula is
CnH2+2
example: methane- CH4
ethane- C2H6
Propane- C3H8
Question:
What are the different structure to represent a organic molecule?
Answer:
1. chemical formula- CH4
2. condensed formula- CH3CH3
3. structural/kekule: shows bonds between atoms
4. line bond
Question:
Which structure of an organic compound does not show bond between the H
and C
Answer:
condensed
, Question:
Which structure of an organic compound is the simplest but requires the
most interpretation?
Answer:
the line bond
Question:
What is inorganic chemistry?
Answer:
the study of (physical and chemical properties) molecules besides carbon
(metals, non metals, minerals)
Question:
What is a functional group
Answer:
an arrangement of atoms that give a molecule a specific physical and chemical
property
