Preferred Label : dipolar compounds;
IUPAC definition : electrically neutral molecules carrying a positive and a negative charge in one of
their major canonical descriptions. in most dipolar compounds the charges are delocalized;
however the term is also applied to species where this is not the case. 1,2-dipolar
compounds have the opposite charges on adjacent atoms. the term 1,3-dipolar compounds
is used for those in which a significant canonical resonance form can be represented
by a separation of charge over three atoms (in connection with 1,3-dipolar cycloadditions).
subclasses of 1,3-dipolar compounds include: allyl type x2y11z-1x-11y12zx11y1z-1x-12y1z1(x,z
c,n,or o;y n oro);
