Question

give reaction of alkanes with hydrogen halogen halides and aqueous solution?​

Answer 1

Answer:

Explanation:

In the first step, a hydrogen molecule reacts with the metal catalyst. This reaction breaks the σ bond between the hydrogen atoms and creates weak hydrogen‐metal bonds. ... This approach of hydrogen atoms to the same face of an alkene molecule is called a syn addition.

Hallogenation

With the addition of a halogen gas and energy, alkanes can be halogenated with the reactivity of the halogens proceeding in the following order: Cl2>Br2>I2.

In this reaction, UV light or heat initiates a chain reaction, cleaving the covalent bond between the two atoms of a diatomic halogen. The halogen radicals can then abstract protons from the alkanes, which can then combine or react to form more radicals. Alkanes can be halogenated at a number of sites, and this reaction typically yields a mixture of halogenated products.
