1. Friedel craft alkyation such as methylation of Nitro benzene did not yield any either meta or ortho and para products; essentially no reaction occurred. However alkylation of phenol (hydroxybenzene ) gave ortho and para methylphenol. Explain

2. Bromination of aniline gives both ortho and para substituted bromo aniline respectively. However, the nitration of the same aniline gives only a meta-nitroaniline upon nitration. Discuss why.

1. It's unclear whether Genie had any mental retardation (either from birth or as a result of her abuse). Why does this fact make her case problematic for deriving clear conclusions about the Critical Period Hypothesis? 2. Does Genie's learning of vocabulary words constitute acquisition of language? Why or why not? If it is language, then why should she have been able to learn some vocabulary, but not able to learn rules of grammar (i.e., syntax and morphology)? 3. Can...
