WebPhenols are organic compounds containing a benzene ring bonded to a hydroxyl group. They are also known as carbolic acids. Phenols react with active metals like sodium, and potassium to form phenoxide. This reaction of phenol with metals indicates its acidic nature. Phenols react with aqueous sodium hydroxide too to produce phenoxide ions. WebShort forms or abbreviations are used while naming the examination of various sectors. The applicant who is willing to attend the exam must have a clear idea about the full name of the exam. For example: CAT – Common Admission Test. IAS – Indian Administrative Service.
