Apne doubts clear karein ab Whatsapp (8 400 400 400) par Why do aldehydes and ketones behave differently? You will remember that the difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. Expressions and Identities, Direct Ketones don't have that hydrogen. However, ketones lack that particular hydrogen atom oxidation process becomes difficult. Hence, it acts as a strong reducing agent.
Because
Statement-II: Ketones do not give Schiff's test. You can imagine that if the H on the aldehyde is smaller than the "C-groups" on the ketone, it is easier to attack the electrophilic carbon on the aldehyde since it is less hindered.

Likewise, after the oxidation of the aldehyde, the carbon chain containing the $\ce{C=O}$ group remains same but due to loss of $\ce{-R}$ group during oxidation, the length of the carbon chain decreases in ketones. Oxidation of aldhydes involved the cleaveage of bond while that of ketones involves the cleavage of C-C bond which is rather difficult. Why are aldehydes more reavtice than ketones towards nucleophilic addition reactions ?
Statement -:II: Aldehydes and ketones undergo intermolecular association due to dipole -dipole interactions. Your IP: 13.238.215.180 The difference between an aldehyde and ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. 1. This difference in property between aldehydes and ketones is used to distinguish them from each other. Statement-I: Ketones are less reactive than aldehydes. MP Board Exam 2021 - MPBSE Reduces Class 10, 12 Syllabus by 30 Percent. The presence of that hydrogen atom makes aldehydes very easy to oxidize (i.e., they are strong reducing agents ).
