$$ \text { From the following, how many compounds contain at least one secondary alcohol?} $$

Choose the correct answer from the options given below :

Given below are two statements :

Statement I : The dipole moment of R-CN is greater than R-NC and R-NC can

Statement II : R-CN hydrolyses under acidic medium to produce a compound which on treatment with $\mathrm{SOCl}_2$, followed by the addition of $\mathrm{NH}_3$ gives another compound $(\mathrm{x})$. This compound $(\mathrm{x})$ on treatment with $\mathrm{NaOCl} / \mathrm{NaOH}$ gives a product, that on treatment with $\mathrm{CHCl}_3 / \mathrm{KOH} / \Delta$ produces R-NC

In the light of the above statements, choose the correct answer from the options given below

The number of possible tripeptides formed involving alanine (ala), glycine (gly) and valine (val), where no amino acid has been used more than once is:

One mole of $\mathrm{Cl}_2(\mathrm{~g})$ was passed into 2 L of cold 2 M KOH solution. After the reaction, the concentrations of $\mathrm{Cl}^{-}, \mathrm{ClO}^{-}$and $\mathrm{OH}^{-}$are respectively (assume volume remains constant)
