When benzene is treated with 2-methylpropene and sulfuric acid, the product obtained is tert-butylbenzene. Propose a mechanism for this transformation. For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer.

See explanation and image attached

Explanation:

This reaction begins when the pi bond in 2-methylpropene is attacked by a proton. A tertiary carbocation is formed which now may attack a benzene ring in an electrophilic reaction. A tertiary carbocation is very stable.

The electrophilic attack of the tertiary carbocation yields the final product  tert-butylbenzene as shown in the image attached.

the answer is 0.8m.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
