Is a methyl group or any other alkyl group (R) considered to be an "ortho & para director" or "meta director"? Explain your answer by:
a. drawing all resonance structures for each position
b. identifying any stabilizing or destabilizing resonance structures.

1. Do all substituted benzenes react differently from benzene? Are they faster or slower?
2. Draw the mechanism arrows depicting the formation of the nitronium ion by an acid-base reaction between H2SO4 AND HNO3. Identify the electrophile that will "nitrate" the unknown aromatic compound.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
