The major product formed in the given reaction is
The Friedel–Crafts alkylation usually involves treating benzene with a t-alkyl chloride and the Lewis acid AlCl3.AlCl3 removes the chlorine atom from t-BuCl and releases the t-Bu cation for the alkylation reaction.
The OH group is said to be ortho, para-directing towards electrophiles. In phenol it is the ortho and para positions that are electron-rich (and, of course, the oxygen itself).
The system with the largest internal pressure is
A compound consists of atoms A and B. Atoms of B form cubic close packing lattice and atoms of A occupy half of octahedral voids and half of tetrahedral voids. What is the molecular formula of the compound?
