Chemistry : Alcohols, Phenols and Ethers

Most acidic is :

Z $\stackrel{\mathrm{PCl}}{\to }$ X $\stackrel{\mathrm{alc}. \mathrm{KOH}}{\to }$ Y $\stackrel{\mathrm{conc}. {\mathrm{H}}_2{\mathrm{SO}}_4}{\to }$ Z

Here Z is :

• CH₃-CH₂-CH₂-OH

• (CH₃)₂-C-OH

• CH₃-CH(OH)-CH₃

• none of above

Compound reacting with alkaline KMnO₄ :

• (CH₃)₃-C-OH

• (CH₃)₂-CH-OH

• (CH₃)₃-C-CH₂OH

• none of the above

Lucas reagent reacts fastest with :

• butanol - 1

• butanol - 2

• 2 - methyl - propanol - 2

• 2 - methyl - propanol - 1

The major product formed in the following reaction is

${\mathrm{CH}}_2\mathrm{CH}\left(\mathrm{Cl}\right){\mathrm{CH}}_2-{\mathrm{CH}}_2\mathrm{OH} \stackrel{\mathrm{aq}. \mathrm{KOH}}{\to }$

• CH₃CH = CH- CH₂OH

• CH₂=CH- CH₂- CH₂OH

• ${\mathrm{CH}}_3-\underset{\mathrm{OH}}{\underset{|}{\mathrm{CH}}}-{\mathrm{CH}}_2-{\mathrm{CH}}_2\mathrm{OH}$
