5. Which of the following molecules is aromatic or anti-aromatic? Support your claim with an MO diagram and checking the molecule against the rules of aromaticity. CH

Is this molecule aromatic? Why doesn't the pi bond in the benzene ring on the left side not count torward aromaticity?

Which of the attached cyclic molecules are meso compounds?

the drawing utility. Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of C6H13Br and two stereogenic centers. Indicate chirality by using wedge and hashed wedge notation. Lone pairs do not need to be shown. edit structure ...

Please provide the hybridization for each carbon.

verse osis Consider the structures of the carbocations formed by ortho attack of the electrophile, *NO₂, on the given starting material. NH2 Part: 0/2 Part 1 of 2 + Draw all resonance structures for the carbocation formed by ortho attack of the electrophile "NO, on the given starting material. If applicable, include the resonance structure in which π bond electrons "move" to the more electronegative atom as a lone pair. Be sure to include all charges and relevant lone pairs. 00 al. Ar B K
