protic solvent
solvents with protons in solution, e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable
steric strain
increase in energy resulting from electron repulsion between atoms that are not directly bonded by occupy the same space
number of oxygen atoms is the same as number of carbon atoms, CxH2x)x
monosaccharide
Trigonal Planer Bent
one lone pair electrons
trigonal pyramidal
one lone pair electrons 107 degrees
tetrahedral bent
two lone pair electrons 104.5
polar covalent bond
unequal sharing of electrons
tetrahedral
109.5, sp3
covalent bond
A chemical bond that involves sharing a pair of electrons between atoms in a molecule nonmetal + nonmetal
trigonal planar
120 degrees, sp2
linear
180, sp
How many of the following compounds contain an ionic bond LiNHCH3, CH3NH2, NaOCH3, BH3
2
ionic bond
Formed when one or more electrons are transferred from one atom to another metal + nonmetal
London dispersion forces
The intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
steric hindrance
The prevention of a reaction at a particular location in a molecule by substituent groups around the reactive site.
aprotic solvent
a solvent that has no acidic protons; a solvent with no O-H or N-H groups
which of the following molecules contain both ionic and covalent bonds NaOH, CH3ONa, C6H5NH3Cl, CH3CH2COK
all of the above
what makes a species less stable and more reactive

dipole-dipole forces
attractions between oppositely charged regions of polar molecules
ion-ion interactions
attractive forces between two charged molecules strongest interaction
