Chemical Foundations

Question 1

2 types of covalent bonds

Answer 1

sigma (σ) bond and pi (π) bond

Question 2

the way that molecules bond has an affect on the chemistry

Answer 2

example:

Ethane

Ethene

Ethyne

Question 3

configuration

Answer 3

spatial arrangement of atoms of molecule has either . . .
- double bond - there is no freedom of rotation
- chiral center

Question 4

conformation

Answer 4

group of atoms have freedom of rotation without breaking any bonds due to freedom of bond rotation

Question 5

stereospecificity

Answer 5

position of atoms in a molecule controls the outcome of a reaction

Question 6

unique rules of carbon (3)

Answer 6

• can form very long chains
• forms chemical bonds with different atoms C, H, O, N
• forms different type of covalent bonds (single, double, triple)

Question 7

covalent bond

Answer 7

chemical bond that involves the sharing of electron pairs between atoms
