Vedclass · Answer

(A) The dehydration of alcohols depends on the degree of substitution of the alcohol:$1$. Primary $(1^{\circ})$ alcohols like ethanol undergo dehydration using concentrated $H_2SO_4$ at $443 \ K$.$2$. Secondary $(2^{\circ})$ alcohols like propan$-2-$ol undergo dehydration using $85 \% \ H_3PO_4$ at $440 \ K$.$3$. Tertiary $(3^{\circ})$ alcohols like tert-butyl alcohol undergo dehydration using $20 \% \ H_3PO_4$ at $358 \ K$.Therefore,$X = H_2SO_4, 443 \ K$; $Y = 85 \% \ H_3PO_4, 440 \ K$; $Z = 20 \% \ H_3PO_4, 358 \ K$.

Identify the reagents $X, Y, Z$ for the following dehydration reactions of alcohols:
$CH_3-CH_2-OH \xrightarrow{X} CH_2=CH_2 + H_2O$
$CH_3-CH(OH)-CH_3 \xrightarrow{Y} CH_3-CH=CH_2 + H_2O$
$(CH_3)_3C-OH \xrightarrow{Z} (CH_3)_2C=CH_2 + H_2O$
