What is the reason for the solubility of low molecular weight carboxylic acids in water?

The major product of the following reaction is $CH_3CH=CHCO_2CH_3 \xrightarrow{LiAlH_4}$

Carboxylic acids are more acidic than phenol and alcohol because of

The yield of alkyl bromide obtained as a result of heating the dry silver salt of carboxylic acid with bromine in $CCl_4$ is:

Identify the product $B$ in the following reaction.
$C_6H_5COCl + H_2O \rightarrow B + HCl$

Assertion $(A)$: Carboxylic acids are more acidic than Phenols.
Reason $(R)$: Resonance structures of carboxylate ion are equivalent,while resonance structures of phenoxide ion are not equivalent.
