In order of OH goup acidity:
ethanol<water<phenol<carboxylic acid
OH group acidity varies because of
the stability of the R-O- ion
More stable R'-O- ions are ____ acidic
These arise because of:
more
Arise because of delocalisation of electrons across the ion
Iron chloride gives ______ when reacted with a ____

||
O
Ethyl Ethanoate
Hydrolysis of esters goes to completion with
alkali i.e. dilute sodium hydroxide

does not go to completion
When a molecule interacts with electromagnetic radiation
it can vibrate, rotate, translate or electronic changes
In infrared spectroscopy changes are in
vibrational energies of the molecules
Wavenumber =
1/wavelength :cm3
Wavelength =
h :um
Frequency =
