Explicit Lone Pairs
-
Checker searches for explicitly drawn lone pairs (inserted as Special node from the Advanced tab of the Periodic Table).
-
Fixer offers removing the explicit lone pair (
removeatom).Example :
Explicit Lone Pairs checker ( explicitlp)Warning: Fix Delete Atom ( removeatom)Detect Explicit Lone Pair
