What are the four rules for writing resonance structures? 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple bond. The latter compromise conjugated unsaturat...

What do you call a carbon when it is a substituent? Correct Answer Methyl - Attached to 3 Hs Primary - Attached to 1 R Secondary - Attached to 2 R Tertiary - Attached to 3 R What does alkyl mean? Correct Answer It refers to an alkane. What are some physical properties of alkanes? Correct Answer The more Cs, the higher the MP and BP What does branching to do an alkane? Why? Correct Answer INCReases the MP DECReases the BP Branched alkanes are more compact which weaken Van Der Waals ...

Lewis dot structure: steps Correct Answer 1. Find total # of valence electrons for all atoms in molecule 2. Use one pair of electrons to form one bond between each atom 3. Arrange remaining electrons around atoms to satisfy duet for H and octet for other atoms Exceptions to octet rule Correct Answer 1. B, Be: may have less than an octet 2. Atoms with an odd number of electrons 3. Atoms in the 3rd period or greater (with d orbitals available for hybridization) may have greater than an octe...

Order of highest priority functional groups Correct Answer carboxylic acid > anhydride > ester > amide > aldehyde > ketone > alcohol > alkene > alkyne > alkane Ketose Correct Answer sugar containing ketone Aldose Correct Answer Sugar that contains an aldehyde group Carboxylic acid derivatives Correct Answer esters, amides, anhydrides, carboxylate Constitutional isomers Correct Answer structural isomers, have same molecular formula but differ in the covalent...
