Hint: Try to recall that wurtz reaction is used for the preparation of symmetrical alkanes and alkenes contains pi bond. Also, it is known to you that soda lime is a mixture of solutions and pentane has three different isomers. Now, by using this you can easily answer the given question.
Complete step by step solution:
-In order to find which statement is true, you need to discuss each option given in question. The inspection of options are as follows:
-Option A: It is known to you that soda lime is a mixture of chemicals. It is composed of calcium hydroxide and sodium hydroxide and is prepared by mixing powder calcium hydroxide with affine mist of sodium hydroxide solution. So, option A is false.
-Option B; It is known to you that in a wurtz reaction, two alkyl halides molecules are coupled in presence of sodium metal in anhydrous to form a new carbon-carbon. Made. It is limited to the preparation of symmetrical alkanes with even number of carbon atoms only. So, option B is also not the correct option to the given question.
-Option C; It is known to us that alkenes contain pi bond and the carbon attached to pi bond is sp2 hybridised. So, option C is also not the correct option to the given question.
-Option D: Also, it is known to you that pentane has three structural isomers and one of which is neopentane. On monochlorination, neo pentane yields three different mono-chloro derivatives. So, this is the correct option.
Therefore, from above we can conclude that option D is the correct option to the given question.
Note:
-It should be remembered to you that if dissimilar alkyl halides are used, a mixture of alkanes is formed. It is usually difficult to separate the mixture and hence, wurtz reaction is not a suitable method to synthesize unsymmetrical alkanes.
-Also, you should remember that soda lime is used to remove carbon dioxide from breathing gases and prevent carbon dioxide retention.
