Answer 1

> All answers are conect. is Grignard Reagent (2.1) Rmg x organomagnesium halide = Any * = allylic hydrogen - ® Due to two resonana structure, allylic radicals are more stable, uv. o visible I Conjugation used to indicate - Phenyl o Huckel suhe require (40+2) IT clectrons for an cromatic compound Benzene aromaticity does not undergo addition due to exomaticity which gives them extra stabilitay. Benzene substitution rather than addition reaction MO undergo - 3 qt can't delocalized therefore the to double bond us is alated. / and 2 can These are conjugated delocalized.
