I want to produce 2sec monostable pluse with cd4073..

thanks
 
There is an answer for that. Yes AND no.

Yes because it's possible to do. No because a 4073 (like most digital cmos chips) does not have an accurate voltage window where it is garanteed to threat the inputs as either low or high.
You can do, but you need a pot and have a lot of fail/success (using a stop watch or other method for timing a pulse).

Also NO because it will work under the condition where the trigger event is a source that is shifting from low to high and then stays high. You can't make a fully working monostable that takes a short pulse input and having an output staying for more time when you're only allowed to use and gates.
 
The 4073 wouldn't be my choice, but if that's all you've got then how about this?

....or if you're dealing with negative-going pulses there's this simpler circuit:
