The major product in the reaction

Halogenation of which one of the following will yield m-substituted product with respect to methyl group as a major product?

The correct order of melting points of hydrides of group 16 elements is

Given below are two statements:

Statement I : Phenols are weakly acidic

Statement II : Therefore they are freely soluble in NaOH solution and are weaker acids than alcohols and water

Choose the most appropriate options:

Hydrolysis of which compound will give carbolic acid?

Compound I is heated with Conc. HI to give a hydroxyl compound  A which is further heated with Zn dust to give compound B. Identify A and B.

An organic compound (A) (molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_2$ ) was hydrolysed with dil. ${\mathrm{H}}_2{\mathrm{S}\mathrm{O}}_4$ to give a carboxylic acid (B) and an alcohol (C). ' $C$ ' gives white turbidity immediately when treated with anhydrous ${\mathrm{Z}\mathrm{n}\mathrm{C}\mathrm{l}}_2$ and conc. $\mathrm{H}\mathrm{C}\mathrm{l}$ . The organic compound $\left(\mathrm{A}\right)$ is:

Product ‘A’ of following sequence of reaction is
