When 2-methylpropene is bubbled into dilute sulfuric acid at room temperature, it appears to dissolve. What new substance has been formed?

i am not able to get the proper name but i can tell the structure i.e.

ch3
ch3-ch2-ch2oso3

No, this is the wrong structure.

To determine the new substance formed when 2-methylpropene is bubbled into dilute sulfuric acid, we need to consider the type of reaction taking place.

In this case, the reaction is an addition reaction, specifically an acid-catalyzed hydration reaction. The double bond in 2-methylpropene (C₄H₈) undergoes addition with water (H₂O) in the presence of sulfuric acid (H₂SO₄) as a catalyst. The reaction can be represented as follows:

C₄H₈ + H₂O → C₄H₁₀O

This equation shows that the double bond in 2-methylpropene is broken, and a hydrogen atom from water adds to one carbon atom, while a hydroxyl group (-OH) adds to the other carbon atom. As a result, a new substance called 2-methyl-2-propanol (also known as tert-amyl alcohol) is formed (C₄H₁₀O).

Thus, when 2-methylpropene is bubbled into dilute sulfuric acid at room temperature, it undergoes an addition reaction and forms 2-methyl-2-propanol.
