yes phenol does show hydrogen bonding.the delocalized electron ring attracts the lone pair electrons of oxygen of hydroxyl group as along with the bonded electron pair of the o2 with the benzene ring.being more electronegative than the h2-atom it takes the bonding electron cloud in between towards him. so the total charge of the o2 atom rises to negative.so the o2 atom becomes negatively charged & the H2 atom becomes positively charged.they become polar and at this state phenols can make in between them & with the water too.in case of making H2-bond the spatial arrangement of hydroxyl group should let only to make bonds in between 2/3 phenol due to the steric body of benzene.in case of phenol only one side in a huge structure is capable to make H2 bond and the rest doesn't. but the delocalized electron cloud of benzene ring should make the hydroxyl polarization stable and it can also attract another body of benzene in phenol by arranging their spatial arrangement in such a way that they have opposite magnetic pole towards them originated due to the rotation of delocalized electron cloud within the benzene ring.these all are just my assumptions.
According to the definition, to form a hydrogen bond, a bond with hydrogen and another element should have a higher value for electronegativity such as H-N, H-O and H-F. H-Cl does not meet with sufficient polarity to form a hydrogen bond.
Hydrogen bonding is a type of intermolecular force of attractionAdded:This is between molecules.It is not as strong as chemical bonding within molecules (intramolecular) though.
the hydrogen bonding is possible in oxygen, nitrogen,and fluorine
NH3 exhibits hydrogen bonding in addition to dispersion forces. This significantly increases the intermolecular force, and raises the boiling point. PH3 does not exhibit hydrogen bonding and the dominant intermolecular force holding these molecules together is dispersion forces. (Dispersion forces also known as Van Der Waal Force)
The hydrogen bonding present between the two molecules is known as intermolecular hydrogen bonding, the molecules may be similar or may be dissimilar. The molecules having intermolecular hydrogen bonding have high melting and boiling points and low volatility. They are more soluble in water as compared to the molecules having intramolecular hydrogen bonding.
FON Remember this as it mean only hydrogen bonded to fluorine, oxygen and nitrogen will exhibit hydrogen bonding H2O ( water ) = hydrogen bonding as hydrogen is bonded to oxygen CO ( carbon monoxide ) = no hydrogen bonding Think electronegative differences.
Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will not exhibit hydrogen bonding. However, methanol has carbon, hydrogen and oxygen and therefore, can exhibit hydrogen bonding. As a result, using the 'like dissolve like' approach we can see why methane will be insoluble in water but methanol will be soluble.
Otho nitro phenols have intra cellular H bonds.Para nitro phenols have inter cellular H bonds.
Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.
The bond between hydrogen and fluorine is polar covalent and it can exhibit hydrogen bonding.
Covalent bonding and some of these bonds (C-O and O-H) are polar.
molecule cotaining hydrogen and electronegative atoms form hydrogen bonding
flourine oxygen and nitrogen forms hydrogen bonding with hydrogen

nope, there's no hydrogen bonding because the hydrogen is not bonding whit any fluorine, just with the carbon
The intramolecular hydrogen bonding can be determined by
