Ans:
Main reason for many of the unique property of water is it has ability to form Hidrogen bonding.
Due to this reason it can be exist as liquid when compared to other molecules of same group.
Due to this reason it can be exist as liquid and gas
Due to this same reason it can ne form bonds with almost all the compounds.
Due to this reason it's act as universal solvent which means it has the capacity to dissolve most of the substances in it
So answer is it has ability to form Hydrogen bonding.
Option D is answer.

The reason for many of the unique properties of water is: dispersion forces that are present...
h of the following statements is NOT true? London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...
Water has significant IMF, which result in many of its unique properties—high boiling point relative to its molecular weight, high surface tension, strong capillary action. Draw the molecular structures for six water molecules and show how they might organize themselves due to hydrogen-bonding. Show the H-bonds with dotted lines.
C1. Water Water has a number of unique properties that are essential for life. Most of these properties are as a result of the polar nature of water and its ability to form hydrogen bonds. Using your knowledge on the properties of water, answer the questions below. a) Why is it important for water to be a liquid over a broad range of temperatures? [2 marks] b) Why is water referred to as polar and why does its polarity affect...

Water is one of the most important compounds for life because of many properties. Identify one of those properties from the choices below. a. low heat capacity b. good solvent for hydrophobic compounds such as lipids c. ice is much more dense than liquid water d. linear, non polar molecule that can form hydrogen bonds between oxygen and carbon e. cohesion with other water molecules
Consider the molecule below: o=s=o: Select ALL the intermolecular forces that are expected to be present between two of these molecules. Select as many answers as are applicable, however points will be deducted for incorrect guesses. Select one or more: Dispersion forces Dipole/dipole forces Hydrogen bonding Check What amount of thermal energy (in kJ) is required to convert 136 g of ice at -16 °C completely to water vapour at 217 °C? The melting point of water is 0°C and...
2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
