a. PhCOH(3) overset(NaOCI)underset(NaOH)...

a. `PhCOH_(3) overset(NaOCI)underset(NaOH)rarr PhCOONa+CHCl_(3)`
b.
Both have `(-COCH_(3))` group, but haloform is formed in (a) only, Explain.

Text Solution

Verified by Experts

Due to the steric hundrance of two `(-CH_(3))` groups in the ortho position w.r.t. `(-COCH_(3))`, in (b), `CHCl_(3)` is not formed in (b).
