A when sulfuric acid is added to sirie, hydrager
irga5000 [103]

Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.

                         H2SO4 (l) H2O (g) + SO3 (g).

The reaction is highly exothermic as an enormous amount of heat is liberated.

The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.

An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.

Draw the major organic product of the regioselective reaction of 2-methyl-2-pentene with H2O in presence of H2SO4. You do not ha
hodyreva [135]

Answer:

2-methyl-2-pentanol is produced as a major product

Explanation:

  • Double bond in 2-methyl-2-pentene is protonated first by consuming a proton from H_{2}SO_{4}.
  • A carbocation intermediate is formed after protonation of double bond. Most stable carbocation is formed as a major intermediate.
  • Here a tertiary carbocation is formed as a major intermediate.
  • H_{2}O gives subsequent nucleophilic addition to the carbocation intermediate and produce 2-methyl-2-pentanol as a major product.
  • Reaction mechanism and major organic product has been shown below.
