Question

CH4=C2H2=CH3-COH=CH3-CH2OH=CH3-CH2-Br

Answer 1

CH4->C2H2->CH3-COH->CH3-CH2OH-> CH3-CH2-Br

2 CH4 = C2H2+3 H2

C2H2+H2O = CH3-COH

CH3-COH+H2 = CH3-CH2OH

CH3-CH2OH+HBr = CH3-CH2-Br

Answer 2

The series of compounds you provided are as follows:

1. CH4: Methane
2. C2H2: Ethyne (also known as acetylene)
3. CH3-COH: Ethanol (also known as ethyl alcohol)
4. CH3-CH2OH: Ethanol (also known as ethyl alcohol)
5. CH3-CH2-Br: Bromoethane

Let me know if there's anything specific you would like to know about these compounds or if you have any other questions!
