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.

Vitride has the formula NaAlH2(OCH2CH2OCH3)2. it can be added to alkyl bromide / magnesium solutions to start a gringnard reaction.

Vitride has the formula NaAlH2(OCH2CH2OCH3)2. it can be added to alkyl bromide / magnesium solutions to start a gringnard reaction. however it is a hydride source and is capable of adding to the c=o bonds in addition to reacting with water. these questions pertain to an organic lab I did. we prepared an gringnard reaction of 0.05g (0.021 moles) Mg with 2.5mL (0.023 mol) of 1-bromobutane and 1.8mL(0.0197 moles) of 2-methylpropanal as the electrophilie. 1) As a preventative measure,...
