"OH" group attached to aromatic ring is electrons donor because it has two lone pairs of electrons on oxygen atom which may involve in resonance process, but "OH" group attached to saturated carbon act as electrons attracting group due to high electronegativity of oxygen.

What is a functional group of atoms such as OH called?
Radical
Who Evidenced the existence of subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutheford, 1919
How much in the impulse increase if an object is doubled?
oh oh u have to go to the hospital fast ....u got the drips
What is the formula for Hydroferricyanic acid?
Ferric means iron is in the +3 state; hydroxide means the anion is the OH- ion. So the whole formula is Fe(OH)3.
A picometer pm is equal to 1 multiplied by 10 to the negative 12 power m. OH bond lengths in water are 95.8 pm while S-H bond lengths in dihydrogen sulfide are 135 pm. Why are S-H bond lengths longer?
A picometer (pm) is equal to 1 x 10^-12 m. The O-H bond lengths in water are 95.8 pm,while S-H bond lengths in dihydrogen sulfide are 135 pm. Why are S-H bonds longer than O-H bonds? Is it because Sulfurs mass is greater than Oxygens mass? Please correct me if I'm wrong. Oxygen = 15.99 Sulfur = 32.06
What substituents have a negative Hammet substituent constant?
Substituents with a negative Hammet substituent constant are electron donating. Examples include R groups and OH groups.
Do basic compounds produce OH- ions when dissolved in water?
Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.
What is the base in a reaction?
The base in a chemical reaction is the species that either (a) accepts a proton, (b) produces an OH- ion, or (c) is an electron donor.
Why is the nitro group a meta director?
nitro group is very electronegative,so it withdraws electron from the benzene ring so as to destabalize the carbocations in the ortho- and para- position. Nitro group is also fairly bulky so steric hinderance limits the formation of ortho product.ok?
Is phenol acid or base?
Phenols are acidic in aqueous solution. The oxygen atom off of the benzene ring acts as an electron donating group, and pulls the electron density towards the benzene ring and away from the hydrogen atom. This makes the hydrogen easily extracted by free floating H2O molecules. Because of this, H3O+ molecules form, and this is equivalent to H+ which can show a low pH, which is characteristic of acidic solutions.
What is alcohol functional group?
Hydroxyl group, -OH
Where does the extra electron in OH come from?
When a bond in water molecule H20 breaks it forms H+ and OH-. The extra electron comes from H. H-O-H ------> H+ + OH-
What is -OH group?
The -OH group is called the hydroxyl group
What does Clemmensen reduction do to OH group?
Aldehydes and ketones haven't an -OH group.
What group is an -OH group?
hydroxyl
What do all alcohols have in common?
The hydroxyl group (-OH) is the functional group that defines alcohols.
Why two OH groups on one carbon atom are unstable?
OH groups a strongly electron withdrawing. The effect of two of these groups on a single carbon is that it causes de-shielding of the carbon nucleus making the carbon atom a strong electrophile. The carbon then attacks the lone pair of one of the hydroxyl groups, forming a C, O double bond and expelling a proton and a hydroxide ion which form water.
