Question

2-Methylpropane-1,2-diol ($CH_3-C(CH_3)(OH)-CH_2OH$) is subjected to oxidative cleavage using periodic acid ($HIO_4$). What are the final isolated organic products of this specific reaction?

Prashant Kotian · Accepted Answer

Correct answer: A. Periodic acid () cleaves the bond of vicinal diols. The carbon with the tertiary alcohol group (bonded to two methyls) oxidizes to a ketone (propanone / acetone). The carbon with the primary alcohol group oxidizes to an aldehyde (methanal / formaldehyde).
