Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Weak attraction between a partially positive hydrogen and a partially negative oxygen or nitrogen some distance away; found in proteins and nucleic acids
A
Ionic Bond
B
Covalent Bond
C
Hydrogen Bond
D
Peptide Bond
Explanation: 

Detailed explanation-1: -Hydrogen bonding: This is a special kind of dipole-dipole interaction that occurs specifically between a hydrogen atom bonded to either an oxygen, nitrogen, or fluorine atom. The partially positive end of hydrogen is attracted to the partially negative end of the oxygen, nitrogen, or fluorine of another molecule.

Detailed explanation-2: -hydrogen bond: A weak bond in which a hydrogen atom in one molecule is attracted to an electronegative atom (usually nitrogen or oxygen) in the same or different molecule. covalent bond: A type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.

Detailed explanation-3: -In some polar molecules that contain hydrogen atoms, the partial positive charge of the hydrogen atoms of one molecule are attracted to the partial negative charge of an atom of a nearby molecule. This force of attraction is called a hydrogen bond.
