Consider the reactions:

A compound that does not undergo S_N1 reaction with OH^- is:

1.		2.
3.		4.

Wurtz reaction is not preferred for the preparation of alkanes containing an odd number of carbon atoms because:

The correct sequence for increasing dipole moment is:

1. CCl₄ < CHCl₃ < CH₂Cl₂
2. CHCl₃ < CH₂Cl₂ < CCl₄
3. CCl₄ < CH₂Cl₂ < CHCl₃
4. CH₂Cl₂ < CCl₄ < CHCl₃

A hydrocarbon C₅H₁₀ does not react with chlorine in the dark but gives a single monochloro compound C₅H₉Cl in bright sunlight. Hydrocarbon could be:

The above-mentioned compounds that react faster in S N₂ reaction with OH^- from each given pair respectively are:
1. CH₃Br, CH₃I
2. CH₃Br, (CH₃)₃CCl
3. CH₃I, CH₃Cl
4. CH₃I, (CH₃)₃CCl
