- In which species (NO3- or CH3NO2) are the N-Obond(s) longer? In which species (NO3- or CH3NO2) are the N-Obond(s) weaker?a) Sighting down the C3-C4 bond, draw the gauche (60 degrees) and anti (180 degrees) Newman projections of 2,4-dimethylhexane. b) Circle the conformation that you drew that is lower energy.Conformer E is a (cis/trans) isomer. A conformational ring flip of conformer E will yield conformer F in which the substituent on carbon 1 will be (axial/equatorial/neither) and the substituent on carbon 3 will be (axial/equatorial/neither). Conformer (E/F) will be more stable.
