Question

Match List-I with List-II 



Choose the correct answer from the options given below:

• (A) (III), (B) (I), (C) (II), (D) (IV)
• (A) (I), (B) (III), (C) (II), (D) (IV)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (IV), (B) (III), (C) (II), (D) (I)

Hint:

Aniline is an activator and ortho/para-directing, nitrobenzene is deactivating and meta-directing, chlorobenzene is mildly activating and ortho/para-directing, and allenes have central sp hybridization.

Answer 1

The Correct Option is B

- Aniline (A): Aniline is an activating group and ortho/para-directing because the amino group donates electron density to the ring.
- Nitrobenzene (B): The nitro group is a deactivating group and meta-directing due to its electron-withdrawing nature.
- Chlorobenzene (C): The chlorine group is a mild activating group and ortho/para-directing due to its lone pairs, but it also withdraws electron density via induction.
- Allene (D): Allene has a central sp-hybridized atom, making it linear.
Step 2: Conclusion.
Thus, the correct matching is: \[ \text{(A) (I), (B) (III), (C) (II), (D) (IV)} \]
Final Answer: \[ \boxed{\text{(A) (I), (B) (III), (C) (II), (D) (IV)}} \]
