The smallest ketone and its next homologue are reacted with NH₂OH to form oxime
A.two different oximes are formed
B.three different oximes are formed
C.two oximes are optically active
D.all oximes are optically active✓ Correct
Explanation
The smallest ketone and it is next homologous are reacted with 2 NH OH which leads to the formation of three types of oxime. The three types of oximes are: The smallest ketone is acetone and its next homologue is butanone Hence, the correct answer is option (b) 10. A mixture of benzaldehyde and formaldehyde on heating with aqueous NaOH solution gives (a) benzyl alcohol and sodium formate (b) sodium benzoate and methyl alcohol (c) sodium benzoate and sodium formate (d) benzyl alcohol and methyl alcohol This reaction is a cross-Cannizzaro reaction and the reaction involved will be ( .) 6 5 6 5
