Question

CH3-CH3->CH3-CH2CL->C4H10->CH2=CH-CH2-CH3

Answer 1

СН3-СН3+Сl2= CH3-CH2-Cl + HCl (hv)
CH3-CH2-Cl+2Na+ Cl-CH2-CH3 -> C4H10+2NaCl
C4H10 -> CH2=CH-CH2-CH3 + H2 (t, kat)

Answer 2

The given sequence represents a series of chemical reactions starting with ethane (CH3-CH3) and ending with 1-butene (CH2=CH-CH2-CH3). Let's break down each step of the reaction:

1. CH3-CH3 → CH3-CH2Cl: In this step, ethane (CH3-CH3) reacts with chlorine (Cl2) in the presence of ultraviolet (UV) light or heat to form ethyl chloride (CH3-CH2Cl). This reaction is known as a substitution reaction, where one of the hydrogen atoms in ethane is replaced by a chlorine atom.

2. CH3-CH2Cl → C4H10: The second step is not specified in the given sequence. Without further information, it's unclear how ethyl chloride (CH3-CH2Cl) is converted into butane (C4H10). Additional details are required to determine the specific reaction involved.

3. C4H10 → CH2=CH-CH2-CH3: The final step involves the conversion of butane (C4H10) into 1-butene (CH2=CH-CH2-CH3). This reaction is an elimination reaction known as dehydrogenation, where one of the hydrogen atoms is removed from butane to form a double bond between two carbon atoms. The resulting compound is 1-butene (CH2=CH-CH2-CH3).

Please provide more information about the second step, or if you have any other specific questions.
