hydrogen decomposes quickly when exposed to light. the reaction for decomposing hydrogen peroxide is:
Svet_ta [14]

The decomposition reaction for hydrogen peroxide is given below:

                                     2H_{2} O_{2} → 2H_{2} O + O_{2}

This is a decomposition reaction.

Reactions in which a reactant breaks into two or more products are known as Decomposition reactions.

                                          AB → A + B

here, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction

The decomposition reaction of decomposing hydrogen peroxide is exothermic. When the hydrogen peroxide undergoes a decomposition reaction, heat is also released along with water and oxygen.

Hence the  reaction for decomposing hydrogen peroxide is :

         2H_{2} O_{2} → 2H_{2} O + O_{2}

Aleks [24]
The question is incomplete. Complete question is attached below.
..........................................................................................................................

Correct Answer: <em>Option 1) 2-pentene</em>

Reason:
Following are the IUPAC rules for naming the compound
1) Select the longest carbon chain. In present case longest carbon chain has 5 carbon atom. Hence, it is a pentane derivative.
2) In case of alkene, replace 'e' of alkane by 'ene'
3) Give lowest number to function group. In present case, it is double bond.

Applying above rules, the IUPAC name of compound is 2-pentene
