CE ÎNSEAMNĂ AZIDE ÎN ENGLEZĂ?
Azide
Azida este anionul cu formula N3-. Acesta este baza conjugată a acidului hidrazoic. N3- este un anion liniar care este izoelectronic cu CO2 și N2O. Pe teoria legăturii de valență, azida poate fi descrisă de mai multe structuri de rezonanță, una importantă fiind N = N + = N-. Azida este, de asemenea, un grup funcțional în chimia organică, RN3. Aplicarea dominantă a azidelor este ca un agent de propulsie în pungile de aer.
