Advances in technology have many industries, including agriculture. which agricultural application is most likely to be affected by new advances in dna technology from the human genome project? a researcher who is investigating selective breeding of livestock a farmer who is planning a harvest schedule for genetically modified crops a plant scientist who is modifying the genetic information of crop plants in a laboratory a conservationist who wants to find water sources in drought-prone places

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.

answer carbon and three oxygen atoms;
