JEE Main 5 April 2026, Shift 1, Chemistry Q65

Question 65 of 75 in this shift, Chemistry question 15 of 25, Section A.

For the following Friedel Craft's alkylation reaction, which of the statements are correct? [figure: benzene + n-propyl chloride (CH3CH2CH2Cl\mathrm{CH_3CH_2CH_2Cl}) with anhydrous AlCl3\mathrm{AlCl_3} →\rightarrow Alkylbenzene] A. Major product is n-propyl benzene. B. iso-propyl carbocation intermediate is also generated. C. Multiple substitution is inevitable. D. Introducing electron-donating substituent on benzene will not produce any alkyl benzene. Choose the correct answer from the options given below:
