i) Give the IUPAC name of the product formed when tertiary butyl alcohol is passed over copper heated to 573 K.
ii) Arrange the following in the increasing order of acidity and justify the same: `(CH_(3))_(3)COH, CH_(3)OH, (CH_(3))_(2)CHOH`

Explanation

i) Tertiary alcohols undergo delıydration to form corresponding alkene when passed over heated Cu or Ag catalyst at 573 k
`underset("t - butyl alcohol")(CH_(3)-overset(CH_(3))overset("|  ")underset(CH_(3))underset("|  ")"C "-OH)overset("Cu or Ag")rarrunderset("2 - methyl propene")(CH_(3)-overset(CH_(3))overset("|  ")"C "=CH_(2)+H_(2)O)`
IUPAC name of the product formed is 2 methyl propene
ii) `(CH_(3))_(3)C-OH lt (CH_(3))_(2) CH-OH lt CH_(3)OH`
As the number of `CH_(3)` groups increases, polarity of `O-H` bond decreases.
