What is the correct order of increasing acidity for the following compounds?
$I$: Phenol
$II$: Cyclohexanol
$III$: Cyclohexanecarboxylic acid
$IV$: Ethynylcyclohexane

Among formic acid,acetic acid,propanoic acid and phenol,the strongest acid in water is

$\text{CH}_3\text{COOH} \xrightarrow{\text{LiAlH}_4} \text{X} \xrightarrow{\text{PCl}_5} \text{Y} \xrightarrow{\text{Alcoholic KOH}} \text{Z}$. Find product '$Z$' in the above reaction.

Esterification (shown below) is a reaction converting a carboxylic acid to its ester. It involves only the carbonyl carbon. Esterification of $(-)$ lactic acid with methanol yields $(+)$ methyl lactate. Assuming that there are no side reactions,what is true about this reaction?

Write the chemical reactions of acetic acid $(CH_3COOH)$ with the following reagents:
$(i)$ Excess $Cl_2$ $+$ Red $P$ followed by $H_2O$
$(ii)$ Heating with sodalime $(NaOH + CaO)$
$(iii)$ Electrolysis of its sodium salt ($Kolbe's$ electrolysis)
$(iv)$ Heating with excess ammonia $(NH_3)$
$(v)$ Reaction with $PCl_5$
$(vi)$ Reaction with $PCl_3$
$(vii)$ Reaction with $SOCl_2$
$(viii)$ Heating with $P_2O_5$
$(ix)$ Reaction with $NaOH_{(aq)}$
$(x)$ Reaction with $NaHCO_{3_{(aq)}}$
$(xi)$ Reaction with $Na$ metal
$(xii)$ Reaction with $LiAlH_4$ / ether or $BH_3$
$(xiii)$ Reaction with ethanol $(C_2H_5OH)$ in the presence of $H_2SO_4$ or $HCl$ gas

The product $(B)$ of the reaction is:
