If Nitrobenzene has a larger dipole moment then aniline and phenol but is much less soluble in water?

aniline and phenol can form hydrogen bonds with water molecules through their -NH2 and -OH groups, while nitrobenzene has no available hydrogens, but in principle can form hydrogen bonds with its oxygens with water hydrogen.
As a matter of fact, the first option is more favorable than the second (e.g. butanol CH3CH2CH2CH2-OH is slightly more soluble than butanal CH3CH3CH2HC=0 in water, and the difference in solubility increases at increasing alkyl chain length).
On a qualitative basis, one can think that aniline and phenol are more similar to water than nitrobenzene, hence they are more miscible.

Why o-chlorophenol has less dipole moment than o-fluorophenol?
The reason for the larger dipole moment of o-fluorophenol is because F is more electronegative than Cl.
What is the difference between dispersion forces and dipole- dipole forces?
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
Why don't dipole dipole forces have much effect on a gas?
The ratio of the average distance between molecules to the size of the molecules themselves is much larger in a gas than in either a liquid or a solid of the same substance, and each dipole is contained in a single molecule. Therefore, the dipole-dipole forces must act over much longer distances in a gas, and all electrostatic forces, such as dipole-dipole forces, are weaker over long distances than over short ones.
Is cyclohexanol soluble in water and why?
it is slightly soluble in water .because the presence of OH group enables it to dissolve in water but the non polar cyclic carbon atoms do not allow it to dissolves completely
Which is more soluble in water CH3NH2 or H2S?
NH3(g), also known as ammonia gas, is highly soluble in water, to the tune of 89.9g/L at 0 degrees celsius. This high solubility is due to the electronegativity of the nitrogen. Being a gas, the solubility improves as the temperature drops.

Which of these molecules has an overall dipole mome?
An overall dipole moment is H2S.
What is a perfect dipole?
A perfect (or pure) dipole is the contrary to a 'physical' dipole. The Physical (electric) dipole consists of two equal and oppsite charges (+/-)q, separated by a finite, and well defined distance, d.The perfect dipole is a model (or an approximation) for the physical dipole, where we say that d is ~equal to zero. This is legit when we observe the dipole (measure the electric field, E, or the potential, V) at distances, r, far greater than d, and simplifies our equations for E(r,t) and V(r,t).
What trend is NOT seen in polymers as they get larger?
As polymers get larger the trend that is not seen is that they are are easy to process. This is not the trend because as polymers get larger, their solutions begin to develop a high viscosity, they become less soluble, and they become difficult to process.
Ion-dipole attractions are stronger than dipole-dipole attractions because why?
ion-dipole attractions are stronger because they have a larger charge. the bigger the charge, the stronger the attractive force. induced dipole-induced dipole as weak Van der Waal's forces and even smaller charge....less than 1 usually, hence weaker.
Why alkyne has larger dipole moment than alkene?
Because in Alkyne,each C atom is sp hybridised(50% s character) and so has more electronegativity and hence more dipole moment.But in alkene, each atom is sp2 hybridised(33% s character) and hence lesser electronegativity
Why so2 has a higher boiling point than CO2?
obviously S03 idiot cause it has a higher IMF due to its dipole to dipole and more oxygens. even so, it has a higher mass and you should at least check wikipedia lol, it has the numbers WHOEVER wrote the above comment is stupid. SO3 doesnt have dipole dipole retard cuz it isn't polar. The fact that SO3 has a higher b.p. than SO2 is b/c the LDF (London dispersion force) of SO3 is a greater IMF than the dipole-dipole force of SO2.
Why is KCL soluble in water?
KI is more soluble in water because I is bigger than Cl, meaning that the atomic radius is larger and therefore the bond is weaker. Solubility is higher with weaker bonds because they break easier.
Why do some covalent bonds have a permanent dipole?
Some covalent bonds have a permanent dipole because, in these bonds, the shape of the 50 % probability space for finding an electron is larger near one end of the bond than near the other end. In pre-quantum terms, the electrons are more attracted to the nucleus at one end of the bond than to the nucleus at the other end.
What all does the digestive system do?
The digestive system break down larger insoluble food molecules into smaller soluble one. hope this helps lily-may
