Chem ch. 12-2 Flashcards
sigma bonds (signal carbon)
C can share valence with 4 different elements for single bond. the strongest.
can only be 1 bond (alpha 1)
sigma
aliphatic hydrocarbons (alpha is first) AND also known as…(parfin and alph)
open, no rings - also known as parafins - also known as saturated
olefin (ol’ fin is keen to be un)
alkenes - unsaturated
acetylenes
is ethyne. unsaturated hydrocarbons
aromatic (benz smells good)
benzene
constitutional isomers
same formula but different connections. alcohol and ethers are isomers.
only exists when there is a C-C bond. (conform to the carbon bonds)
conformation
When tetra = 0 it’s called…(tetra moon)
or on top of each other, it’s called eclipsed
tetra (or dihedral) (hide tetris)
is the angle from the H you see and the one behind it.
when tetra is about 60 degrees
it’s called staggered
primary carbon (1 with circle on top) (primarily last)
the carbon that is attached to only 1 other carbon. All the carbons at each end of the molecule
secondary carbon - (2 with a circle on top)
attached to 2 more other carbons.
tertiary carbon - (3 with a circle above it)
attached to 3 more carbon.
quaternary carbon - (4 with a circle at top)
attached to 4 more carbons.
C4H10 - format of formula? (you see the molecules)
molecular formula - you see the number and type
c-c-c-c - format of formula?
extended formula
CH3 - CH2 - CH2 - CH3 OR CH3 (CH)2 CH3 (these 2 are the same) format of formula?
condensed structure
/-/ = - format of formula?
line structure
line facing me
wedge
line projecting away
dashes
_____
ethane line structure
constitutional isomers
think butane - drawn as C-C-C-C and C-C-C and one C on top.
n-butane
normal butane - the butane isomer that is a straight chain
