A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
A bond that forms between a positively charged hydrogen atom of one molecule and a negatively charged region of another molecule is a hydrogen bond. Hydrogen bonds are weak attractions between a slightly positive hydrogen atom and a slightly negative atom (like oxygen or nitrogen) in another molecule.
Water is polar because of the difference in electronegativity between oxygen and hydrogen, and the shape of the molecule. Each H-O bond is polar, and, because of the large, electronegative oxygen atom, the molecule is bent so that the partially negative oxygen atom is at one pole of the molecule and the partially positive hydrogen atoms are at the opposite pole of the molecule.
A hydrogen bond is formed between the proton (H+) and the ammonia molecule (NH3). In a hydrogen bond, the hydrogen atom of one molecule is attracted to the electronegative atom of another molecule.
since hydrogen atom has no electron in its shell, it acquires positive charge. when a negatively charged atom comes in contact with hydrogen atom, it donates h atom a electron to make a covalent bond. but when it breaks the negative atom restores its electron.
A water molecule is polar because there is an uneven distribution electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen ofatoms.
Intramolecular hydrogen bonding: Occurs within a single molecule, where a hydrogen atom is shared between two electronegative atoms. Intermolecular hydrogen bonding: Forms between different molecules, where a hydrogen atom of one molecule is attracted to an electronegative atom of another molecule. Dipole-dipole hydrogen bonding: Involves the interaction between the positive end of one polar molecule and the negative end of another polar molecule through hydrogen bonding.
the bond between two water molecule is hydrogen bond.
A hydrogen bond is formed between the oxygen atom in water and a hydrogen atom in ammonia. This interaction occurs because of the attraction between the partially positive hydrogen atom in ammonia and the partially negative oxygen atom in water.
An intermolecular hydrogen bond forms between different molecules, while an intramolecular hydrogen bond forms within the same molecule. For example, water molecules form intermolecular hydrogen bonds with each other, whereas in the case of ethanol, the -OH group in the same molecule can form an intramolecular hydrogen bond.
The reason why it is advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phoshate and deoxyribose groups in a DNA molecule is because the strong covalent bonds running along the "ladder" of the DNA molecule (the phospate and deoxyribose units) keep the molecule together during its existence and more importantly its reproduction. The weak hydrogen bonds in the middle keep the reproduction cycle going on forever because it is able to perform an easy split between the hydrogen bonds throughout the middle of the molecule.
