NEET 2019 · ChemistryPrevious Year Question

An alkene "A" on reaction with $O X_{3}$ and $Zn - H X_{2} O$ gives propanone and ethanal in equimolar ratio. Addition of $HCl$ to alkene "A" gives "B" as the major product. The structure of product "B" is:

Answer: (C) $H X_{3} C - CH X_{2} - C (CH X_{3}) (Cl) - CH X_{3}$ .

A. $Cl - CH X_{2} - CH X_{2} - CH (CH X_{3}) - CH X_{3}$
B. $H X_{3} C - CH X_{2} - CH (CH X_{2} Cl) - CH X_{3}$
C. $H X_{3} C - CH X_{2} - C (CH X_{3}) (Cl) - CH X_{3}$ ✓
D. $H X_{3} C - CH (Cl) - CH (CH X_{3}) - CH X_{3}$

Correct Answer

(C) $H X_{3} C - CH X_{2} - C (CH X_{3}) (Cl) - CH X_{3}$
