Question

Q.Q. Draw the major product(s) for the nitration of the following substrates OOH OCH3 NH2 CN CH2CH3

Answer 1

solution: ОН H₂sou a NO2 HNO₃ Cook group is ring deactivating group and meta directing group so incoming gp. is substituted at meta position to-coon group. NH2 NH2 H₂SO4 HNO3 NO2 -NH₂ group is sing activating and ortho- para directing group. +R effect is dominate over the - I effect so, para products is major produce SN ON Hy sou HNO 3 ſi NO2 / - CN group is sing deactivating and meta-directing group and .cl group is ring activating and ortho-para directing group so incoming group is substitute at para to the all group or mets to the -CN group.

Осиз 2 L CH₂CH3 H₂SO4 HNO3 - CH₂ CH₂ NOZ - OH3 groef is sing activating and orthopala directing group and -CH₂ CH3 is also orthor para directing group so incoming group goes on the pare position of och group because treffect of ochz poup is dominate over the - I effect. C CH3 group also act tI effect. at it ostho-position.
