G Atrazine is an herbicide that is commonly used to control weeds in corn, sorghum, and sugarcane fields. Atrazine is a six membered heterocyclic ring with nitrogen at positions 2, 4, and 6. Carbon 1 is single bonded to chlorine. Carbon 3 is single bonded to an N H group which is single bonded to C H 2, C H 3. Carbon 5 is single bonded to N H which is single bonded to a carbon single bonded to two methyl groups. Atrazine Atrazine binds at the Q B site of the D2 subunit, blocking electron flow from Q A to Q B , competing with Q B for the binding site on D2. Identify the statements inferred from this information.

for points guys

i think that the answer is c

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.
