Comprehension Type
Direction (Q. Nos. 15-19) This section contains 2 paragraphs, each describing theory, experiments, data, etc. Five questions related to the paragraphs have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).
Passage I
An unknown organic compound A is determined to have molecular formula C6H12O and passing it through chiral column does not separate it into enantiomers. A does not react with Br2 nor with cold, dilute alkaline KMnO4. Heating A with concentrated H2SO4 gives product B (C6H10) which can be separated into enantiomers. Ozonolysis of a single enantiomer of B produces C, an optically active keto-aldehyde of formula C6H10O2 which gives positive iodoform test.
Q.
Structure of B that satisfy the above criteria is
