C? H? → possible structure of C? H? are; CH? -C (CH? )=CH? and CH? -CH=CH-CH?
(Unsaturation factor = 1)
Ozonolysis of CH? -C (CH? )=CH? gives acetone (B) and formaldehyde.
Oxidation of CH? -C (CH? )=CH? with KMnO? /H? gives acetone (B) and CO?
The question states it gives C? H? O (B). Hence the alkene is 2-Methylpropene (A).

(a) Phenol with Br? / H? O gives 2,4,6-tribromophenol. (High ionisation due to polar solvent and high activation of ring)
(b) Phenol with Br? in CS? /CHCl? /FeBr? gives a mixture of o- and p-bromophenol, with p-bromophenol as the major product. (less ionisation due to non- polar solvent)

Conjugate base is highly stable.
Acidic strength ∝ stability of conjugate base.
