What is the IUPAC name of Glycerol?

A 0.5 M aqueous \(\mathrm{H}_2 \mathrm{SO}_4\) solution is diluted from 2 litres to 20 litres. The concentration of the resulting solution will be

The number of moles of hydrogen oxidized in the oxidation of 67.2 L of H 2 at STP is:

Read the following passage given below and answer the question.
Aldehydes and ketones undergo nucleophilic addition reactions. A nucleophile attacks the electrophilic carbon atom of polar carbonyl group from perpendicular to plane of \(sp^2\) hybridised orbitals of carbonyl carbon. The hybridisation of carbon changes from \(sp^2\) to \(sp^3\) and a tetrahedral alkoxide intermediate is formed. This captures \(H^+\) to give neutral product. In carboxylic acids, carbonyl carbon is less electrophilic than carbonyl carbon in aldehydes and ketones.
An organic compound \(C_3H_6O\) does not give a precipitate with 2,4-dinitrophenylhydrazine and also does not react with metallic sodium. It could be :

The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. The five d orbitals in an isolated gaseous metal atom/ion have same energy, i.e., they are degenerate. This degeneracy is maintained if a spherically symmetrical field of negative charges surrounds the metal atom/ion. However, when this negative field is due to ligands (either anions or the negative ends of dipolar molecules like NH3 and H2O) in a complex, it becomes asymmetrical and the degeneracy of the d orbitals is lifted. It results in splitting of the d orbitals. The pattern of splitting depends upon the nature of the crystal field.

If \(A=\left[\begin{array}{cc}a \cos \theta & b \sin \theta \\ -b \sin \theta & a \cos \theta\end{array}\right]\), then \(A^{-1}\) is equal to:

Let \(f(x)=\left\{\begin{array}{ll}\frac{|x|}{x}, & x \neq 0 \\ 1, & x=0\end{array}\right.\), and \(g(x)=\left\{\begin{array}{ll}x \sin \frac{1}{x}, & x \neq 0 \\ 0, & x=0\end{array}\right.\). Then at the origin, which one is true?
