DNA is negatively charged because of the phosphate group that is in each nucleotide. DNA also has a negative charge because of the phosphate icons in its chemical backbone.â¦.
A nucleophile can be any negative ion or any neutral molecule that has at least one unshared electron pair. Nucleophile is a substance that is very electropositive, therefore, like to interact with positive centers. It can initiate reactions using the lone electron pair.For example, when a nucleophile reacts with an alkyl halide, the lone pair of the nucleophile attacks the carbon atom that bears the halogen. This carbon atom is partially positive charged due to the electronegativity difference between it and the halogen atom.or example, when a nucleophile reacts with an alkyl halide, the lone pair of the nucleophile attacks the carbon atom that bears the halogen.
