4.(06.01 HC) Two methods of biotechnology used by scientists are described
below.

Process A: Inserted a pesticide gene into a soybean

Process B: Used plants and microorganisms to create a new biofuel

Which process is likely to be more advantageous in conservation? (4 points)

O Process B because it will reduce our dependency on fossil fuels

OProcess A because it will increase the number of pests in the environment

O Process B because it will cause an increase in fossil fuel pollution

O Process A because more food will increase the global population

the answer is c. nacl

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.
