aldehyde1612:
On that photocopy sheet... where u said with hot KMno4 will give a carboxylic acid or ketone....
do u mean that the CH2 will be removed and replaced by O (i know theres bond breaking/formings etc.. but for visual aid) and the double bond on the CH2 will also be replaced by a O... giving two carboxylic acids ??
... or just the double becomes a single and then forms a carboxylic and ketone...???
