Out of the following alkenes, the one which will produce tertiary butyl alcohol on acid catalysed hydration is

Which of the following species can act as the strongest base?

Assertion (A): p-methoxyphenol is a stronger acid than $p$-nitrophenol.

Reason (R): Methoxy group shows + I effect whereas nitro group shows -I effect.

Which of the following alcohols will not undergo oxidation?

For the pair phenol and cyclohexanol, answer the following

(a) Why is phenol more acidic than cyclohexanol?

(b) Give one chemical test to distinguish between the two.

(a) (i) Why is the $$\mathrm{C}-\mathrm{O}$$ bond length in phenols less than that in methanol?

(ii) Arrange the following in order of increasing boiling point:

Ethoxyethane, Butanal, Butanol, n-butane

(iii) How can phenol be prepared from anisole? Give reaction.

OR

(b) (i) Give mechanism of the following reaction:

$$\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{OH} \xrightarrow[413 \mathrm{~K}]{\mathrm{H}_2 \mathrm{SO}_4} \mathrm{CH}_3 \mathrm{CH}_2-\mathrm{O} -\mathrm{CH}_2 \mathrm{CH}_3+\mathrm{H}_2 \mathrm{O}$$

(ii) Illustrate hydroboration - oxidation reaction with an example.
