Which of the following are 3,5 (meta) directing groups when second group is induced in them:
i) -NH3
ii) -CHO
iii) -COOH
iv) -CH3
- A
ii, iii, iv
- B
ii, iii
- C
i, iv
- D
i, ii, iv
The 3 5 directing groups or Meta directing groups are as follows:
Aldehyde (-CHO), Ketone (-CO-), Ester (-RCOOR’), Carboxyl Group (-COOH) etc.
Because the carbon in these groups is partially positive hence it withdraws the electrons.
Other than them Nitro groups, Nitriles, Sulphones etc are also called meta-directing groups.
As per the explanation, this option is incorrect.
