The most suitable reagent for the conversion of R CH ₂ OH R CHO is

Options

  1. AKMnO ₄
  2. BK ₂ Cr ₂ O ₇
  3. CCrO ₃
  4. DPCC (pyridine chloro chromate).

Correct answer

D. PCC (pyridine chloro chromate).

Step-by-step solution

Pyridine chloro chromate (PCC) [ C ₅ H ₅ NH ⁺ ClCrO ₃⁻ ] selectively oxidizes primary alcohols to aldehydes. Secondary alcohols can be oxidized to ketones with PCC.
