Alkene $R-CH=CH_2$ reacts readily with $B_2H_6$ and the product on oxidation with alkaline hydrogen peroxide produces:

Write the products of the addition reaction $ >C = C < + XY \to $

Consider the following reactions. What is $A$?
| Reaction | Observation |
| :--- | :--- |
| $A \ (C_7H_{14}) \xrightarrow{\text{ozonolysis}} B + C$ | |
| $B \xrightarrow{I_2 + NaOH, \Delta} \text{yellow ppt}$ | |
| $B \xrightarrow{Ag_2O, \Delta} \text{silver mirror}$ | |
| $C \xrightarrow{I_2 + NaOH, \Delta} \text{no yellow ppt}$ | |
| $C$ $\xrightarrow{LiAlH_4} D$ $\xrightarrow{\text{anhydrous } ZnCl_2, \text{conc. } HCl} \text{white turbidity within 5 minutes}$ | |

Ethylene is a member of the $.....$ series.

Which hydrogen in compound $(E)$ is easily replaceable during bromination reaction in the presence of light?
$CH_3 - CH_2 - CH = CH_2$
$(E)$

In the presence of peroxide,hydrogen chloride and hydrogen iodide do not give anti-Markovnikov addition to alkenes because:
