Is acetone an end product of fermentation?

NO!!!! Definitely not.

The end product of fermentationa is ethanol and carbon dioxide.

Ethanol's old name is ethyl alcohol , commonly referred to as alcohol; the stuff that you drink in beers wines and spirits.

The chemical formula for ethanol is 'CH3-CH2-OH' .

Acetone is the old name for propanone. propanone is a ketone and a powerful organic solvent. It smells like 'pear drops' sweets/candy'.

The chemical formuls for propanone is 'CH3-C(=O)-CH3.

Two things to note are;-

1. The number of carbons in the chain.

2. The double bonded 'C=O' in propanone, which does not occur in ethanol.

NB To ferment a sugar to form alcohol (ethanol), use the enzyme , yeast, a little water, a temperature of 37oC ; it is a temperatutre senstive process. and in anaerobic ( No air/oxygen) conditions.).
