Aspirin can be prepared by the reaction of

Given below are two statements :
Statement $I :$ The esterification of carboxylic acid with an alcohol is a nucleophilic acyl substitution.
Statement $II :$ Electron withdrawing groups in the carboxylic acid will increase the rate of esterification reaction.
Choose the most appropriate option

In the reaction sequence:
$CH_3-CH(OH)-COOH$ $\xrightarrow{\Delta } [Y]$
$[Y]$ will be:

Assertion : $\beta$-Keto carboxylic acids lose $CO_2$ when heated at about $370 \ K$.
Reason : An enol is first formed by loss of $CO_2$,but it readily tautomerises to the more stable ketone.

The descending order of acidity for the following carboxylic acids is:
$A.$ $CH_3COOH$
$B.$ $F_3C-COOH$
$C.$ $ClCH_2-COOH$
$D.$ $FCH_2-COOH$
$E.$ $BrCH_2-COOH$
Choose the correct answer from the options given below:

The compounds that produce $CO_2$ with aqueous $NaHCO_3$ solution are:
$A$. Benzoic acid
$B$. Phenol
$C$. $2,4,6$-Trinitrophenol (Picric acid)
$D$. Cyclohexanecarboxylic acid
$E$. $4$-Methoxyphenol
