Step by step solution

01

Analyzing Reaction (A)

For reaction (A), we have \(2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{I} \stackrel{\text { Na /ether}}{\longrightarrow} \mathrm{C}_{4} \mathrm{H}_{10}+2 \mathrm{NaI}\). This reaction involves using sodium metal in the presence of ether and results in the formation of a new carbon-carbon bond. This is a well-known reaction called the Wurtz reaction.
02

Analyzing Reaction (B)

As Reaction (B) is not given, we'll ignore this part.
03

Analyzing Reaction (C)

For reaction (C), we have \(\mathrm{R}_{2} \mathrm{CuLi} \stackrel{\mathrm{R}^{\prime} \mathrm{X}}{\longrightarrow} \mathrm{R}-\mathrm{R}\). In this reaction, an organocopper reagent formed from an organolithium compound reacts with an alkyl halide to produce a new carbon-carbon bond. This reaction is known as Corey-House Synthesis.
04

Analyzing Reaction (D)

For reaction (D), we have \(\mathrm{CH}_{3}-\mathrm{CO}-\mathrm{CH}_{3} \stackrel{\mathrm{Zn}-\mathrm{Hg} / \mathrm{HCl}}{\longrightarrow} \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3}\). In this reaction, a ketone undergoes reduction in the presence of amalgamated zinc and hydrochloric acid, resulting in an alkane. This reaction is called the Clemmensen Reduction.
05

Identifying the Correct Option

Now, let's look at the options given: (a) This option incorrectly identifies reaction (A) as the Ulmann reaction and reaction (C) as the Grignard reaction. (b) This option correctly identifies all reactions: (A) as the Wurtz reaction, (C) as Corey-House Synthesis, and (D) as the Clemmensen Reaction. (c) This option incorrectly identifies reaction (C) as the Frankland reaction. (d) This option incorrectly identifies reaction (A) as the Wurtz-Fittig reaction. So, the correct answer is option (b).
