Once again the output molecule is in an arrangement which is difficult to achieve.
This level is very generous with how the bonding tiles work. This means you don't have to be very careful about bonding as you might suspect.
If you place two oxygen and two hydrogen atoms in a square on the bonder tiles and call Bond+, the bonders will make the correct molecule due to the way the game prioritises bonding. This saves a lot of the effort of arranging the molecules carefully. Just plop one of each input down, unbond the lot and then call a single Bond+.
