Ch.4 Organic Chemistry is the Study of Carbon Compounds Flashcards
Organic chemistry
The study of carbon compounds (organic compounds)
What are the major elements of life?
C, H, O, N, S, and P
Valence
The bonding capacity of a given atom; the number of covalent bonds that an atom can form
What are the four main atoms in organic molecules?
Hydrogen, oxygen, nitrogen, and carbon
What gives carbon covalent compatibility with many different elements?
Its electron configuration
What are the four ways that carbon skeletons can vary?
Length, branching, double-bond position, and presence of rings
Hydrocarbons
Organic molecules consisting of only carbon and hydrogen (are nonpolar and thus hydrophobic)
When hydrocarbons undergo reactions, what occurs?
They release a relatively large amount of energy
Isomers
Compounds that have the same number of atoms of the same elements, but different structures and hence, different properties
Structural isomers
Differ in the covalent arrangement of their atoms
Cis-trans isomers
DIffer in the arrangement about a double bond due to the inflexibility of double bonds
Cis isomer
The two x’s are on the same side
Trans isomer
The two x’s are on opposite sides
Enantiomers
Isomers that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon, one that is attached to four different atoms or groups of atoms
Functional groups
A specific configuration of atoms commonly attracted to the carbon skeletons of organic molecules and involved in chemical reactions
