Which type of bond makes it possible for a macromolecule to interact with great specificity with just one out of the many thousands of different molecules present inside a cell?

A. Covalent bonds
B. Noncovalent bonds
C. Hydrogen bonds
D. Ionic bonds

Non covalent interactions.

Explanation: The non covalent interactions can be defined as the interaction among molecules based on the variation among the electromagnetic radiations.

These molecules are not attached to each other based on the sharing of the electrons.

These interactions are Van der Waals, electrostatic, hydrophobic interactions.

The interaction among the molecules is important in order to maintain the three dimensional structure of compound such as carbohydrates and protein molecules.

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.
