(a) Predict the products of the following reactions: (i) CH_3 CH_2 OH → Cu / 273 K (ii) C_6 H_5 OH → Br_2( aq )

Predict the products of the following reactions:

$\displaystyle \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH} \xrightarrow{\mathrm{Cu} / 273 \mathrm{~K}}$

$\displaystyle \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{OH} \xrightarrow{\mathrm{Br}_{2}(\mathrm{aq})}$

Give reasons for the following:

p-nitrophenol is more acidic than p-methylphenol.

$\displaystyle \left(\mathrm{CH}_{3}\right)_{3} \mathrm{C}-\mathrm{Br}$ on reaction with $\displaystyle \mathrm{NaOCH}_{3}$ gives alkene as the main product and not an ether.
