Finals Flashcards
Typical number of bonds for carbon, nitrogen, and oxygen in most neutral organic molecules
C = 4
N = 3
O = 2
Ionic bonds result from the transfer of electrons from metal to
non metal
It has the same placement of atoms but different arrangement of electrons
Resonance
Definition for a bronsted lowry acid
proton donor
The stronger the acid, the smaller the
pKa
Weakest acid
HF
Most acidic to least acidic
triple, double, and single bond
Inductive effect favors
Strong acid
Why do heteroatoms confer reactivity on a particular molecule
Because they have lone pairs and create electron-rich sites on carbon
why do pi bonds confer reactivity on a particular molecule?
because pi bonds are easily broken in chemical reactions
Acyclic alkanes have two fewer H atoms than cyclic alkanes with the same number of carbons
False
Cyclic alkanes have two fewer H atoms than acyclic alkanes with the same number of carbons
True
Rotating the atoms on one carbon by 60 degrees converts an eclipsed conformation into a staggered conformation and vice versa
True conformation of acyclic alkanes
Staggered and eclipsed conformations are
equally unstable
Gauche conformations are generally higher in energy than
anti conformations
