Biochemistry (Module 1) Flashcards
Review of Organic Chemistry
It is the study of carbon-containing compounds except CO2, CO3 HCO3 and CN and doesn’t include the study of minerals, dyes, etc.
Organic Chemistry
It is the characteristic of carbon where it can share 4 valence electrons and form 4 strong covalent bonds.
Tetravalence
The property of carbon that allows it to bond to itself through covalent bonds, forming long chains and rings of different sizes.
Catenation
Because of its electronegativity, carbon can form stable bonds with other elements, primarily H, O, P, S, N and other halogens.
What is the electronegativity of carbon?
2.5
Closeness in EN enables Carbon to form strong covalent bonds.
[True or False]
True
Carbon can hybridize, forming double and triple bonds with atoms like Carbon and Nitrogen only.
[True or False]
False.
Carbon can form double and triple bonds with C, O, S, and N.
It is the three-dimensional space where an electron is found 90% of the time.
Orbital
Each electron shell consists of a specific number of orbitals.
[True or False]
True
The four kinds of orbitals.
s, p, d, f
Orbitals that are spherical and the nucleus are located at the center.
s orbitals
Dumbbell-shaped orbitals. Its nucleus is located at the middle.
p orbitals
Orbitals that are shaped like elongated dumbbells and has its nucleus at the center.
d orbitals
Orbitals are grouped in shells of increasing size and energy.
[True or False]
True
Different shells contain the same number and kinds of orbitals.
[True or False]
False
Different shells contain different numbers and kinds of orbitals.
Each orbital can be occupied by three electrons.
[True or False]
False
Each orbital can be occupied by two electrons.
