Well played indeed, but from wiki https://en.wikipedia.org/wiki/Tetrahydrofuran https://en.wikipedia.org/wiki/Tetrahydrofuran "Odor: Ether-like". As a side note, ether is a lovely smell diluted but inhaled concentrated (for recreational purposes – it's a bit like alcohol in effect) it's bloody brutal, burning your nose & lungs. (They used to be sweets in the UK called Victory V's which contained a very small amount of ether, and they were just lush. Bought some recently and found whatever additives that was had been removed, oh woe :) )
