Achemistry journal requires that all new research papers be peer reviewed by other scientists before they are published. this allows which of the following?
the reviewers can determine the experiment’s feasibility.
the reviewers can determine the experiment’s validity.
the reviewers can include their own findings with the research.
the reviewers can determine if they will fund the research.

The answer is: The reviewers can determine the experiment’s validity.

Peer review is used to maintain quality standards, validity, point to sources of error and improve performance.  

Work on project is evaluated by people with similar competences (qualified members of a profession within the relevant field) as the scientist who are performing the work.

It is common in the field of health care.

Consensus is general agreement, but not necessarily unanimity.

Consensus is achieved through communication at conferences, the publication process, replication and peer review.  

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.
