Question

Which of the following sequence of reaction (reagents) can be used for conversion of `C_(6)H_(5)CH_(2)CH_(3)` into `C_(6)H_(5)CH=CH_(2)` ?
A. `SOCl_(2), H_(2)O`
B. `SO_(2)Cl_(2)` alc KOH
C. `Cl_(2)//hv , H_(2)O`
D. `COCl_(2)` , alc KOH

Answer 1

Correct Answer - B
`C_(6)H_(5)CH_(2)CH_(3)overset(SO_(2)Cl_(2))underset(-SO_(2),-HCl)rarr C_(6)H_(5)-CHCl-CH_(3)overset(alc KOH)underset(-HCl)rarr C_(6)H_(5)CH=CH_(2)`
