Nettet13. feb. 2024 · In a SMILES string, any unfulfilled valency of an atom is assumed to be Hydrogen. For example, writing a simple C means that it’s actually a CH 4 (Methane) and not an elemental Carbon. Similarly, N is NH 3 (Ammonia) and O is H 2 O (Water). To represent elemental atoms, a [] (Square bracket) notation is used. NettetNitration is used to add nitrogen to a benzene ring, which can be used further in substitution reactions.

NettetSubstituents in the benzene ring, such as amino groups (-NH2) and hydroxy groups (-OH), are known to be electron-donating groups. When there is a nitrogen or oxygen atom in the alkyl chain, electrons are pulled due to electronegativity, resulting in a lower electron density.
