I'm trying to understand how the acceptor site works, and the difference with acceptor count.
From an old post I saw that acceptor site will count the lone pair on an atom. However if I try to count the number of acceptor site in a molecule like CCOCC, Marvin Sketch displays 1 acceptor count; and 1 acceptor site. Even if the oxygen atom has 2 lone pairs.
So in which situation the acceptor site is different from acceptor count?
PS: I don't have a problem with donor count and donor site
Yes, the potential hydrogen bond ability of an atom proportional with its lone pair count .
A similar question about the acceptors: https://www.chemaxon.com/forum/viewpost31044.html&highlight=acceptor#31044
There have been a bug in the result output ,therefore, it is strange to figure out how the acceptor calculation is done. I have fixed this bug . The fixed version will be available in the 5.12 version in December.
The difference between the acceptor sites / counts are can be seen well on the attached figure. The "Lone pair count" is equal with the acceptor site count. ( halogen is acceptor or not is an optionally adjustable parameter).
Thanks for reporting this bug.
Thank you for the answer and the pictures.
