Question

$1,2,3$- butanetriol undergoes oxidative cleavage of $HI{O}_4$. During this process:

• A. $1$ equivalent of $HI{O}_4$ consumed & $HC{O}_{2}H$ & $H_{3}C-\underset{O}{\underset{||}{C}}-C{O}_{2}H$ are formed
• B. $2$ equivalent of $HI{O}_4$ consumed & $HC{O}_{2}H,HCH=O$ & $C{H}_3-CH=O$ are formed
• C. $3$ equivalents of $HI{O}_4$ consumed & $HC{O}_{2}H$($2$ eq.) & $1$ eq. of $C{H}_{3}C{O}_{2}H$ are formed
• D. $2$ equivalents of $HI{O}_4$ consumed & $2$ eq. of $HC{O}_{2}H$ & $1$ eq. of $C{H}_{3}CH=O$ is formed

Answer 1

Answer: (D)

$2$ equivalents of $HI{O}_4$ consumed & $2$ eq. of $HC{O}_{2}H$ & $1$ eq. of $C{H}_{3}CH=O$ is formed

$HI{O}_4$ is strong oxidation agent it helps in oxidation of adjacent $-OH$ group
