![**4. Provide mechanisms to explain the following reactions. Show all key intermediates and indicate electron flow using arrows.**
a. A methyl alkyne reacts with a proton (H⁺) to form a dimethyl alkene.
b. A linear alkene reacts with H-Br in the presence of water (H₂O) to form a brominated cycloalkane with an additional methyl group.
c. A bicyclic alkenyl compound reacts with water (H₂O) and a proton (H⁺) to form a bicyclic alcohol.

The image depicts the chemical structures for each reaction and emphasizes the need to specify key intermediates while marking the direction of electron flow with arrows. Each reaction involves specific changes to the molecular structure, suggesting mechanisms such as protonation, electrophilic addition, and hydration.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F13f99433-34aa-4e92-8117-34b0d2272faf%2F4099404c-fab7-4d4d-8719-4b5ad6515763%2Fspq9ogp_processed.png&w=3840&q=75)
