Before I answer that, here's how to play ethylenediaminetetraacetates:

The longest word that anyone's actually heard of is electroencephalographically, which is a form of electroencephalograph, an EEG, which is when they put a bunch of wires on your head and the read your brain waves.
How to play electroencephalographically:
- play EL
- turn EL into ELECT
- turn ELECT into ELECTRO
- skip 6 spaces and play AL
- skip 1 space and play GRAPH
- turn ELECTRO------AL-GRAPH into ELECTROENCEPHALOGRAPH

So, what's the longest word that you can actually play on a real Scrabble board? Actually, there are thousands. Because of all of the crazy words allowed in the Scrabble dictionary, there's a theoretically possible way to play almost every possible 15-letter word. I did an in-depth analysis where I analyzed each of the possible words based on their letter frequency, and found that interpenetrated or interpenetrates is the easiest word to play, based just on letter frequency.
How to play interpenetrates or interpenetrated:
- play IN
- skip 3 letters and play PEN
- skip 2 letters and play RATE
- turn PEN--RATE into PENETRATE
- turn IN---PENETRATE into INTERPENETRATE
- add a D or an S for the glorious finish
- INTERPENETRATES
- INTERPENETRATED
- ENTREPRENEURIAL
- IRRATIONALITIES
- INTERDEPENDENCE
- NONINTERFERENCE
- OVERREPRESENTED
- INTERFEROMETERS
- INHOMOGENEITIES
- INTERCOLLEGIATE
- NONINTERVENTION
- REPRESENTATIONS
- REPRESENTATIVES
And the hardest 15-letter words to play in Scrabble, based on letter frequency are PSYCHOLOGICALLY and PSYCHOPATHOLOGY.
