![### Formation of Alkenes from Acetylene
#### Instructions:
Choose the two alkyl bromides and the hydrogenation method that must be used to synthesize the depicted alkenes from acetylene. Enter your answer as two letters in alphabetical order, followed by a number; i.e., ac2, not ca2. Do not use punctuation.
#### Alkyl Halides:
a. CH₃CH₂Br
b. CH₃(CH₂)₄Br
c. CH₃(CH₂)₅Br
d. CH₃(CH₂)₆Br
e. CH₃(CH₂)₇Br
f. CH₃(CH₂)₈Br
g. CH₃(CH₂)₁₂Br
#### Hydrogenation Method:
1. H₂, Lindlar's catalyst
2. Na, NH₃ (l)
#### Alkenes to be Synthesized:
**Alkene #1:**
(Displays a long-chain alkene with a double bond between the middle carbon atoms and a methyl group at the end.)
\[ \text{HC}\]
**Alkene #2:**
(Shows another long-chain alkene with a double bond between the middle carbon atoms and a methyl group at the end.)
\[ \text{HC}\]
Based on the depiction of Alkenes, determine the appropriate alkyl bromides and hydrogenation method necessary for the synthesis.
Ensure the answers reflect the correct order and format as specified in the instructions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b49abb7-22b1-43f4-8ea9-ededd2a6e7a5%2Fe6781b5f-bb88-407d-aef0-024e4f1df075%2Fwkiiefh_processed.png&w=3840&q=75)
