Question

Am nevoie de ajutor la niste reactii de sinteza la chimie
metan-->acid metanitrobenzoic
metan-->acid paraaminobenzoic
metan-->glicina
Va rog urgent! Multumesc anticipat!

Answer 1

A) 2CH4 -> C2H2 + 3H2
3C2H2 -> C6H6
C6H6 + CH3-Cl -> C6H5-CH3 + HCl
C6H5-CH3 + 3[O] -> C6H5-COOH + 2H2O
C6H5-COOH + HNO3 -> (meta) O2N-C6H4-COOH
B) aceleasi reactii pana la C6H5-CH3
C6H5-CH3 + H2SO4 (20°C pentru izolarea pozitiei orto) -> HO3S-C6H4-CH3 + H2O
HO3S-C6H4-CH3 + HNO3 -> HSO3-C6H3(CH3)-NO2
HO3S-C6H3(CH3)-NO2 + 3[O] -> HO3S-C6H3(COOH)-NO2 + 2H2O
HO3S-C6H3(COOH)-NO2 + 3H2 -> HO3S-C6H3(COOH)-NH2 + 2H2O
HO3S-C6H3(COOH)-NH2 + H2O -> HOOC-C6H4-NH2 + H2SO4
C) 2CH4 -> C2H2 + 3H2
C2H2 + 2H2 -> CH3-CH3
CH3-CH3 + HNO3 -> CH3-CH2-NO2 + H2O
CH3-CH2-NO2 + 3Cl2 -> CCl3-CH2-NO2 + 3HCl
CCl3-CH2-NO2 + 3H2 -> CCl3-CH2-NH2 + 2H2O
CCl3-CH2-NH2 + 2H2O/HO- -> NH2-CH2-COOH + 3HCl
