An educated guess is based on past experience. how does a hypothesis express the educated guess? a. the educated guess is not part of the hypothesis b. the educated guess is a conclusion of the hypothesis c. the hypothesis mentions the educated guesses an observation d. the hypothesis states the educated guess in the form of an if-then statement

C. The hypothesis mentions the educated guesses an observation

Your Answer Is D.

The Hypothesis states the educated guess in the form of an if-then statement.

(I just took the test, so the answer is right)

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.
