Indicate the organic structure for the product expected when `2`-methylpropene is heated with acetyl chloride in the presence of anhydrous `ZnCl_(2)`.

Options

A. `CH_(3)-overset(CH_3)overset(|)underset(Cl)underset(|)C-CH_(2) - CO-CH_(2)`
B. `CH_(3) - overset(H)overset(|)underset(CH_3)underset(|)C-CH_(2) - CO-CH_(3)`
C.
D. `CH_(3)-overset(O)overset(||)C-overset(CH_3)overset(|)C=CH_2`

Answer

A

Explanation

`(CH_3)_2C=CH_2 + CH_2 - (CO)-Cl overset(ZnCl_2)rarr (CH_3)_2C(Cl)-CH_2-(CO)-CH_(3)`
This is an example of electrophilic addition reaction. The electrophile that initiates the addition is `CH_(3)-CO^(+)`Addition reaction obeys Markownikoff’s rule.
