in version 4 and above, if you connect to socket socket io automaticlly create a unique socketId. if you have several rooms you must create array of abject and save rooms and it's users(socktIds) in it.

if disconnect a socket you can find easily in that array then you can find the room.

With socket.io 1.0 you can do this with following code:

socket.on('disconnect', function() {
  console.log(socket.rooms);
});

It will output an array of rooms the user was joined to.

Note that each socket automatically joins a room named with this socket's ID. So you might see something like

[ 'hIP6r4z8Ym1n5SQUAAAA', 'my_room_name' ]

in your console.

I don't know what do you mean about room , but if it is a chat app or something like that you can create a variable on socket object like roomID when first connection.

io.sockets.on("connection",function(socket){
    socket.on("new:user",function(userDATA){
        // create variable as roomID on socket.
        socket.roomID = userDATA.roomID
    }); 

    // other events 

    socket.on("disconnect",function(data){
        var roomID = socket.roomID;
        // do what you want to do
    }); 
});
