A compound that shows a distinct colour change on treatment with alcoholic ferric chloride is:

Optically pure $3$-bromopent-$1$-ene upon addition of $1$ mole of ${\mathrm{Br}}_2$ produces a tribromo compound. The number of stereoisomers in the product is -

An organic compound fused with metallic sodium dissolves in water and the solution is divided into two parts, one part is treated with ${\mathrm{FeSO}}_4$, boiled and filtered. In the filtrate, addition of ${\mathrm{FeCl}}_3$ does not produce any precipitate. To the other part, addition of sodium nitro prusside produces violet colour. The organic compound contains.

Arrange the following compounds according to their boiling points.

In the following reactions

 the major product $X$ is

The higher stabilities of the tert-butyl cation over the isopropyl cation, and the trans-$2$-butene over propene, respectively, are due to the orbital interactions involving.
