Which of the following is not correct ?

Options

A. Pyrrole is more basic than pyridine
B. All the C-C bonds in Naphthalene are identical
C. All O,P-orienting groups need not be activating
D. `-CF_3` is meta orienting group

Answer

A, B

Explanation

a) The lone pair of parole is part of `(4n+2)pi` electrons. So it cannot accept `H^(+)`
b) All the C-C bonds in naphthalene are not identical

Bond order `C_1 - C_2 = 1(2)/(3)` , Bond order of `C_2-C_3 = 1(1)/(3)`
So they are not identical (C is not correct answer - as some deactivating groups are also o,p-orienting) (`CF_3 is m-orienting)
