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...

What are the four rules for writing resonance structures? Correct Answer 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? Correct Answer 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 comprom...

MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...
