is phenol more reactive than benzene?
535914
The increased reactivity compared to benzene is due to the lone pair of p-orbital electrons on the oxygen atom in the phenol group. The electron pair is delocalised into the ring structure, activating the ring.

The larger an atom is, the more reactive it will be. ... This makes it easier for the valence electrons to leave the atom and form an ionic bond or to interact with another atom to form a covalent bond. If electrons can leave more easily, then the atom is more likely to react.

The two primary differences, however, are that hydroxyls are scientifically confirmed to be far more reactive than ozone, and they're safe to use with sensitive materials. This means hydroxyls are able to eliminate a much broader range of odors and VOCs as compared to ozone.

Benzoic acid has a pKa of 4.17, while 2-naphthol has a pKa of 9.5. ... Since benzoic acid's pKa is lower than 6.4, it will deprotonate and become soluble in water, while 2-naphthol will remain in the ether because it won't deprotonate.

N2 is less reactive than O2 in most gaseous reactions because there is a strong triple bond between the atoms, all the valence electrons are in bonding orbitals, and more energy is needed to excite them. ... these electrons are of higher energy and unpaired therefore O2 is more reactive.

In phenol, pulling the pz electrons from the oxygen atom into the ring causes the hydrogen atom to be more partially positive than it is in aliphatic alcohols. This means it is much more easily lost from phenol than it is from aliphatic alcohols, so phenol has a stronger acidic property than ethanol.

Secondly , CH3 group in acetaldehyde decreases the positive charge on cabonyl carbon by +I effect to some extect which is not so in the case of formaldehyde, Since , Nu attack is favourable with more positive charge and less hinderance at carbonyl carbon , hence we conclude that formaldehyde is more reactive than ...

Well, caesium is the more reactive, but good luck getting gram quantities of this metal. Caesium is a ROOM temperature liquid, and its much larger size with respect to sodium means that it is by far a more potent reactant. And in fact as we go down the Group 1, the metals become more reactive.

– in alcohols, a hydroxyl group is connected to a carbon atom. – in phenols, —OH is connected to a benzene ring. (The “parent” molecule of this class is also named phenol: PhOH or C6H5OH.) When two carbon groups are connected by single bonds to an oxygen, this is classified as the ether functional group.

Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions.

According to the table of the organic solvent polarity, the relative value for benzene is 0.111 and 0.099 for toluene. However ,theoretically speaking, benzene is non-polar due to its highly structural symmetry, and toluene is polar because of methyl group's electron donating character.

['Benzene is immiscible in water but soluble in organic solvents.', 'It is a colourless liquid and has an aromatic odour.', 'It has a density of 0.87g cm-3. ... ', 'Benzene has a moderate boiling point and a high melting point. ... ', 'Benzene shows resonance.', 'It is highly inflammable and burns with a sooty flame.']

Radius and Reactivity As atomic number increases, so does an atom's radius. The outermost electron is held less tightly and escapes more readily. Therefore, the alkali metal with the higher number is more chemically reactive. This makes francium the most reactive of the alkali metals.

While electron-withdrawing group (such as -Cl,NO2) increases the positive charge on ring, thus deactivates the ring. hence, phenol is more readily attacked by an electrophile.

When phenolphthalein is used as an indicator, NaOH is taken in a burette because then the colour change is from colourless to pink. And this time, it will be easier to observe. On the other hand, if HCl is taken in a burette, colour change will be from pink to colourless which can't be observed in a single drop.

Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom, as it is in an alkoxide ion, but is delocalized-it is shared by a number of carbon atoms in the benzene ring.

Physical and chemical properties of benzene: Benzene being non-polar is immiscible with water but is readily miscible with organic solvents. Upon combustion of benzene sooty flame is produced.
