Per NCERT §9.3.6 (ozonolysis), reductive ozonolysis of an alkene with O₃ followed by Zn/H₂O gives which class of products?
ACarboxylic acids only
BAldehydes and/or ketones
CDiols only
DAcid chlorides only
Answer & Solution
Correct answer: B. Aldehydes and/or ketones
NCERT §9.3.6 ozonolysis: each C of C=C becomes a carbonyl. Reductive workup (Zn/H₂O) gives aldehyde from =CHR and ketone from =CR₂.
