Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
the oxygen end is slightly electropositive
|
|
|
hydrogen bonds hold water molecules together
|
|
|
water molecules are joined through polar covalent bonds
|
|
|
water is a solid at room temperature
|
Detailed explanation-1: -In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.
Detailed explanation-2: -The hydrogen bond in water is a dynamic attraction between neighboring water molecules involving one hydrogen atom located between the two oxygen atoms. Hydrogen bonding forms in liquid water as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule.
Detailed explanation-3: -Cohesion: Hydrogen Bonds Make Water Sticky In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Detailed explanation-4: -The false statement in the given choices is that hydrogen bonds create molecules. The covalent bond is the specific bond that is used to create molecules.
