In which of the following reactions, two products will be formed other than phosphonium ylide `(POPh_3)`

Options

A.
B. `CH_3CHO +Ph_3P = underset(CH_3)underset(| )C -CH_3 to `
C. `Ph - overset(O ) overset(|| ) C - H +Ph_3 P = CH-Ph to `
D. `H- overset(O ) overset(|| ) C-H +Ph_3 P=CH-CH_3 to `

Answer

C

Explanation

Witting reaction
`Ph- overset(O) overset(||) C-H +Ph_3 P =CH-P to Ph - CH = CH -Ph +POPh_3`
