Vedclass · Answer

(C) $HIO_4$ (Periodic acid) is a selective oxidizing agent that cleaves $C-C$ bonds in compounds containing vicinal functional groups such as: $1.$ Vicinal diols: $-CH(OH)-CH(OH)-$ $2.$ $\alpha$-hydroxy carbonyls: $-CH(OH)-C(=O)-$ $3.$ $1,2$-dicarbonyls: $-C(=O)-C(=O)-$ $4.$ $\alpha$-amino alcohols: $-CH(NH_2)-CH(OH)-$ Analysis: $(1)$ $CH_3-CH(OH)-CH_2-OH$ is a vicinal diol. (Oxidized) $(2)$ $CH_3-C(=O)-CHO$ is an $\alpha$-keto aldehyde. (Oxidized) $(3)$ $CH_3-C(=O)-C(=O)-CH_3$ is an $\alpha$-diketone. (Oxidized) $(4)$ $CH_3-C(=O)-CH(NH_2)-CH_3$ is an $\alpha$-amino ketone. (Oxidized) $(5)$ Cyclohexene oxide is an epoxide,not a vicinal diol or $\alpha$-hydroxy carbonyl. (Not oxidized) $(6)$ $CH_3-O-CH_2-CH_2-OH$ is an ether-alcohol. (Not oxidized) $(7)$ $HOOC-CH_2-OH$ is an $\alpha$-hydroxy acid. $HIO_4$ does not typically oxidize $\alpha$-hydroxy acids. (Not oxidized) Thus,compounds $(5), (6),$ and $(7)$ are not oxidized. However,based on the provided options,$(c)$ is the most appropriate choice as it includes the clearly non-oxidizable species.

Which of the following compounds are not oxidized by $HIO_4$?
$(1)$ $CH_3-CH(OH)-CH_2-OH$
$(2)$ $CH_3-C(=O)-CHO$
$(3)$ $CH_3-C(=O)-C(=O)-CH_3$
$(4)$ $CH_3-C(=O)-CH(NH_2)-CH_3$
$(5)$ Cyclohexene oxide
$(6)$ $CH_3-O-CH_2-CH_2-OH$
$(7)$ $HOOC-CH_2-OH$
