1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C4H9OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer. 1-Butanol occurs naturally as a minor product of the ethanol fermentation of sugars and other saccharides and is present in many foods and drinks. It is also a permitted artificial flavorant in t… WebWhen 2.56 g of the non-electrolyte sulfur, S x, was dissolved in 100 g of CS 2 the freezing point was found to be -111.18 o C. a) [5 marks] Determine the molecular weight of S x and hence the value of x.
