Souring of wine occurs when ethanol is converted to acetic acid by oxygen by the following reaction:

c2h5oh + o2 --> ch3cooh + h2o

a 1.00 l bottle of wine, labeled as 8.5% (by volume) ethanol, is found to have a defective seal.
analysis of 1.00 ml showed that there were 0.0274 grams of acetic acid in that 1.00 ml. the density of ethanol is 0.816 g/ml and the density of water is 1.00 g/ml.

a. what mass of oxygen must have leaked into the bottle?

b. what is the percent yield for the conversion of ethanol to acetic acid if o2 is in excess?

i'm wiling to try and you : )

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
