Which of the following pairs are resonance structures to each other? and CH3 CH3 oooo Tooo and and - H₃C H D. CH3CH2* and *CH2CH3
Are the two structures shown in resonance with each other? (meaning, are they resonance structures of each other?) yes O no, they are constitutional isomers resonance is related to electrons, not compounds No answer text provided.
In each of the following ion pairs, determine which ion is
more stable. Use resonance structures to justify your
answers.
C) Etz-CH2 CH-CEN i
A. Consider the following pairs of structures. Designate each
chirality center as (R) or (S) and identify the
relationship between them by describing them as representing
enantiomers, diastereomers, constitutional isomers, or two
molecules of the same compound. Use handheld molecular models to
check your answers.
B. Tartaric acid
[HO2CCH(OH)CH(OH)CO2H] was an important
compound in the history of stereochemistry. Two naturally occurring
forms of tartaric acid are optically inactive. One optically
inactive form has a melting point of 210 − 212 °...

Nitromethane structures:
Consider nitromethane (CH3NO2). Three reasonable lewis structures (resonance structures) can be drawn for this molecule. a. Draw each of the three most reasonable Lewis structures (two of them look almost identical to each other). b. Calculate the formal charges on C, N and O in each of your Lewis structures. c. Give the hybridization on each atom in each resonance structure. d. Will the geometry of the molecule change depending on which resonance structure is the dominant contributor...
