The order of susceptibility of nucleophilic attack on aldehydes follows the order
As the alkyl group increases, carbonyl becomes a weak electrophile and the reactivity becomes low. So, the order is 1∘>2∘>3∘
Which of the follwoing compounds will show positive silver mirror test?
All aldehydes, formic acid give this test. α-hydroxy ketone also give this test because of H-CO- group presence
C2H5CHO and (CH3)2CO can be distinguished by testing with
Which will form two oximes with NH2OH?
Two isomeric oximes are formed when an aldehyde (other than formaldehyde) or a non- symmetrical ketone reacts with hydroxylamine as shown above.
Clemmensen reduction of a ketone is carried out in the presence of which of the following reagent?
Clemmensen reduction of a ketone is carried out in the presence of Zn−Hg with HCl. This reduction converts carbonyl group to methylene group. It is suitable for compounds that are sensitive to alkali.
When sodium formate is heated it gives
Which of the following is used as hypnotic or sedative?
Paraldehyde is the cyclic trimer of acetaldehyde molecule. It is a hypnotic and sedative with anticonvulsant effects.
3-Hydroxybutanal is formed when (X) reacts with (Y) in dilute (Z) solution. What are X, Y and Z
Which one of the following undergoes reaction with 50% sodium hydroxide solution to give the corresponding alcohol and acid?
Benzaldehyde will undergo Cannizzaro reaction on treatment with 50% NaOH to produce benzyl alcohol and benzoic acid as it does not contain α-hydrogen
Acetaldehyde is produced from the following in the presence of aqueous KMnO4 solution
