1.	Give reasons for the following: 1. Ethyl iodide undergoes SN2 reactions faster than ethyl bromide. 2. (±) 2-Butanol is optically inactive. 3. C-X bond length in halobenzene is smaller than C-X bond length in CH3 -X.
Answer» 1. Because in ethyl iodide, iodide being the best leaving group among all the halide ions. Rate of S_N2 reaction ability of leaving group. 2. (±) 2-hutanol is a racemic mixture which is optically inactive due to the external compensation. 3. Due to resonance in halobenzene, it has a smaller bond length value as compared to CH₃ - X.

In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. (i) Assertion and reason both are correct and reason is correct explanation of assertion. (ii) Assertion and reason both are wrong statements. (iii) Assertion is correct but reason is wrong statement. (iv) Assertion is wrong but reason is correct statement.
