Which of the following does not come under the category of colligative properties?

Answer the question on the basis of passage given below :
Formaldehyde is the first member of the aldehydic series. It is present in green leaves of plants where its presence is supposed to be due to the reaction of \(CO_2\) with water in the presence of sunlight and chlorophyll. Commercially, formaldehyde is obtained by the controlled oxidation of methane in the presence of molybdenum oxide (\(MoO\)) acting as a catalyst. Formaldehyde is a constituent of a number of polymers also called resins. These are non volatile solids or semi solids which are obtained directly from certain plants and can be synthesized in the laboratory.
Benzaldehyde is less reactive towards nucleophilic addition reaction than formaldehyde because of:

(B) Glucose is an aldohexose and is also known as dextrose.
(C) Glucose can be hydrolyzed.
(D) Glucose is a reducing sugar.

Which of the following is the correct formula of a colligative property?

Read the passage carefully and answer:
Organic compounds derived from NH3 by replacing one or more H-atoms with alkyl or aryl groups will form primary, secondary and tertiary amines. The common methods which include their preparations are reduction of nitro group, amide group and nitrile group, Gabriel phthalimide synthesis and ammonolysis of alkyl halides. Amines are basic in nature due to the presence of a lone pair of electrons on the nitrogen atom. Important chemical properties of amines include acylation, alkylation and their interaction with nitrous acid. There are various tests which can distinguish different types of amines from each other, for e.g. carbylamine test, Hinsberg's test, coupling reaction etc. Another important class of compounds which can be derived from primary amines is azo compounds. These compounds are intensely colored and widely used as dyes in textile, leather and food industries.
How many different structural isomers that correspond to the molecular formula \(\mathrm{C}_3 \mathrm{H}_9 \mathrm{~N}\) are possible? Out of these, how many will give a positive carbylamine test?

The resistance of 1N solution of four different electrolytes are given below. Arrange them in increasing order of their equivalent conductance values if the same conductivity cell was used to measure the resistance of all the electrolytic solutions:
(A) 250 ohm
(B) 150 ohm
(C) 50 ohm
(D) 280 ohm
Choose the correct answer from the options given below:

 The concentration of aqueous \(NaCl\) solution that can be used in the bloodstream is:
(Given \(R = 0.082\ L\ atm\ K^{-1}\ mol^{-1}\))"

The kinetic energy of an electron in the ground state of a hydrogen atom is K. The values of its potential energy and total energy respectively are :

The value of the determinant \(\left|\begin{array}{ccc}66 & 18 & 36 \\ 1 & 3 & 4 \\ 11 & 3 & 6\end{array}\right|\) is:

In an AC circuit, the instantaneous values of emf and current are \( E = 100 \sin(314t) \) V and \( I = \sin(314t + \pi/3) \) A. The average power consumed in the circuit is:

If \(U_E=\) electric field energy density and \(U_m=\) magnetic field energy density, then
