Some common antiseptics[edit] A bottle of ethanol (95%) - an antiseptic Alcohols Most commonly used are ethanol (60–90%)‚ 1-propanol (60–70%) and 2-propanol/isopropanol (70–80%) or mixtures of these alcohols. They are commonly referred to as "surgical alcohol". Used to disinfect the skin before injections are given‚ often along with iodine (tincture of iodine) or some cationic surfactants (benzalkonium chloride 0.05–0.5%‚ chlorhexidine 0.2–4.0% or octenidine dihydrochloride 0.1–2.0%).

alkyl halide and starting alcohol because of the usual inaccuracy‚ however the results for boiling point and density proved close to 2-bromobutane and 2-Butanol. The boiling range from the week one experiment was 76-118 ◦C‚ which was too large of a range and the alkyl halide had not been completely purified. However‚ the boiling point for 2-butanol alcohol was about 83 ◦C‚ which lies within the range of the starting boiling range. The boiling range for the product was 87-92 ◦C which closely related

germinated seeds decreased with higher concentrations of fuel. In addition‚ biodiesel was also synthesized and its heat of combustion was found through the use of calorimetry. The heat capacity for the calorimeter was based on the heat of combustion for ethanol‚ which was then used to determine the heat of combustion for biodiesel. The average heat of combustion for biodiesel was ∆Hcomb= -13090.83 kJ/mole‚ as opposed to the theoretical value of -11496.6 kJ/mole‚ which resulted in a 13.9% difference. Furthermore

complete nonpolarity. But that explains any differences in solubilities between the two molecules. Polarity also played a role in the alcohol reactions: water‚ which is polar‚ will be insoluble with 1-octanol (which is nonpolar)‚ insoluble with 1-butanol (also nonpolar)‚ and soluble with methanol (polar). But it’s a little more complicated: the carbon chain of each of these organic compounds will always be nonpolar and therefore hydrophobic‚ but as these are alcohols‚ the -OH group‚ which is polar

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)
