Aldehydes and ketones will not form crystalline derivatives with

  • Solution

    Dihydrogen sodium phosphate (NaH2PO4) does not havea lone pair of electrons on the P atom.As such it can notact as a nucleophile and hence does not react with aldehydes and ketones.

Benzaldehyde reacts with ethanoic KCN to give

  • Solution

Urotropine is obtained when ammonia reacts with

  • Solution

    Formaldehyde reacts with ammonia to form hexamethylene tetramine which is also known as urotropine. It is used as urinary tract antiseptic

    6HCHO + 4NH3 → (CH2)6N4 + 6H2O

Pinacolone is

  • Solution

(CH3)2C = CHCOCH3 can be oxidized to(CH3)2C = CHCOOH by

  • Solution

Sodium formate on heating yields

  • Solution

The test used for the distinction of HCOOH and CH3COOH is treatment with :

  • Solution

    The test used for the distinction of HCOOH and CHCOOH3 is treatment with Tollen’s reagent because formic acid can reduce Tollen’s reagent but acetic acid can not.

The reagent (s) which can be used to distinguish acetophenone from benzophenone is (are)

  • Solution

    I2 and Na2CO3 react with acetophenone (C6H5COCH3)to give yellow ppt. of CHI3 but benzophenone(C6H5COC6H5) does not and hence can be used to distinguish between them.

Formalin is an aqueous solution of

  • Solution

    Formalin is an aqueous solution (40%) of formaldehyde.

Benzaldehyde can be prepared by oxidation of toluene by

  • Solution
