How does the molecular structure of water and the concept of hydrogen bonding relate to transpiration pull?

Water is a polar molecule, meaning that the H atoms are slightly negative and the O atom is slightly positive. Due to the polarity of the H2O molecule, it is possible for the water in the xylem to form a long continuous chain (the water molecules are essentially attracted to one another). Therefore, when water diffuses out of the xylem at the top of the stem, it 'pulls' the chain of water up the xylem.

What is the difference between inter-molecular hydrogen bond and intra-molecular hydrogen bond with examples?
inter molecular hydrogen bonding is between one molecule and the neighbouring molecule whereas the intra molecular bonding between the same molecule
What molecular bond is the strongest?
hydrogen bonding in molecules is stronger
Which molecular solid would have the highest melting?
one with hydrogen bonding.
What is the difference between intra-molecular bonding and inter-molecular interaction?
Intermolecular is the bonding between the molecules (what connects them all together) For example dispersion, dipole-dipole, hydrogen bonding (HFON)Intramolecular is the bonding between the atoms like ionic covalent or metallic.For example in a water molecule the intermolecular bonding would be the hydrogen bonding. The non-bonding pairs will connect with other water molecules non-bonding pairs to create a hydrogen bond. Whereas the intramolecular bonding would be covalent. Because that's what joins the individual hydrogen atoms to one oxygen atom.
Is water a giant covalent structure?
No. Water is molecular, H2O. The molecules "clump together" due to hydrogen bonding, but these bonds are much weaker than the covalent O-H bonds
What is the difference between inter-molecular hydrogen bond and intra-molecular hydrogen bond with examples?
inter molecular hydrogen bonding is between one molecule and the neighbouring molecule whereas the intra molecular bonding between the same molecule
What molecular bond is the strongest?
hydrogen bonding in molecules is stronger
Is a hydrogen bond a weak molecular interaction?
No, hydrogen bonding is a strong intermolecular force.
Which molecular solid would have the highest melting?
one with hydrogen bonding.
Why water is unusual?
It has much higher boiling and melting points than would be expected from its molecular size. This is a result of strong hydrogen bonding. Its solid form is less dense than the liquid, because the hydrogen bonding creates a very open structure.
Hydrogen bonding plays a particularly important role in which plant process?
The transpiration-cohesion-tension mechanism

What is the molecular composition of water?
H20 is the molecular composition of water. Two hydrogen atoms and one oxygen atom. The hydrogen atoms are pulled to the oxygen atom through forces called hydrogen bonding.
Does methanol have a higher boiling point than water?
water have inter molecular hydrogen bonding whereas in methanol there is intra molecular hydrogen bonding.the oxygen atom and hydrogen of other molecule have electrostatic force of attraction in water and forms bridge between each other and form an associated structure thus it has more b.p
Does hydrogen gas have a ionic or molecular?
Hydrogen gas is a molecular compound because it is two non-metals bonding. Non-metal + Non-metal = Molecular compound Metal + Non metal = Ionic compound
