WebIn NH₃, N is more electronegative than H, so the N atom has a partial negative (δ⁻) charge. It also has a lone pair of electrons. In a molecule like CH₃CH₂-Br, Br is more electronegative than C, so C-1 has a partial positive (δ⁺) charge. The lone pair on the N can attack the δ⁺ carbon on CH₃CH₂Br: H₃N: + Br-CH₂CH₃ → H₃N⁺- CH₂CH₃ + :Br⁻ WebApr 6, 2024 · The bonds created between oxygen and phosphorus atoms are negative, which makes the phosphate backbone negative.
