produces OH⁻

Explanation:

The region labelled X on the left circle containing the base is characterized by a substance that produces OH⁻ ions in solution.

Region X is exclusive to bases alone.

  • Based are substances that produces hydroxyl ions OH⁻ in aqueous solutions.
  • Aqueous solutions of base tastes bitter
  • The solutions of bases have a soapy feel
  • They have a pH greater than 7.

Jane made this picture to represent a chemical reaction: Two circles, one white and the other gray are shown on the left. A smal
7nadin3 [17]

It represents a decomposition reaction because one reactant breaks apart and forms two products.

Explanation:

The type of chemical reaction depicted by Jane represents a decomposition reaction because on reactant breaks apart and forms two products.

In this reaction XY breaks apart to form X and Y. This is a decomposition reaction.

                     XY   →   X + Y

  • Decomposition or cracking is the formation of two or more products from a single reactant.
  • The break down of a compound into individual atoms or molecules falls into this category.
  • The extreme instability of a compound drives such a reaction.
  • The products is usually stable or it can dissociate further till it is stable.

An alkene with the molecular formula C8H16 undergoes ozonolysis to yield a mixture of (CH3)2C=O and (CH3)3CCHO. The alkene is:
aalyn [17]

Answer:

2,4,4-trimethyl-2-pentene yields mixture of (CH_{3})_{2}C=O and (CH_{3})_{3}CHO

Explanation:

In ozonolysis (hydrolysis step involve a reducing agent such as Zn, Me_{2}S etc.), a pi bond is broken to form ketone/aldehyde.

Ketone is formed from di-substituted side of double bond and aldehyde is formed from mono-substituted side of double bond.

Ozoznolysis involves two consecutive steps : (1) formation of ozonide, (2) hydrolysis of ozonide.

Hydrolysis can be done with/without using reducing agent. Carboxylic acid/carbon dioxide/ketone is produced when hydrolysis is done without using reducing agent.

Here, 2,4,4-trimethyl-2-pentene yields mixture of (CH_{3})_{2}C=O and (CH_{3})_{3}CHO

Reaction steps are shown below.
