The r-cooh compound behaves as an acid base alcohol ester

Option (a) is the correct answer.

Explanation:

An organic compound that contains "-COOH" as the function group is known as carboxylic compound.

A carboxylic compound is an acid as it dissociates to give hydrogen ion.

Whereas a compound with functional group "-OH" is known as alcohol.

And, a compound with general formula RCOOR' is known as an ester.

Thus, we can conclude that the R-COOH compound behaves as an acid.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
