Answer:
I don't think you can go on without doing a reaction since you touch really anything so no you can not go without any chemical reaction I think this is the answer
Answer:
b
Explanation:
b because it's a physical change
Answer:
Adiabatic. This is a process where no heat is being added or removed from the system. Or can be simply stated as: no heat transfer (or heat flow) happening in a system.
Explanation:
The complete reaction along with intermediates is given below, with each step highlighted in different color.
Step 1: In this step an acidic proton at alpha position is abstracted from lactone moiety and corresponding enolate is formed, which is resonance stabilized. Both structures are shown. In this case LDA (<span>Lithium diisopropylamide) acts as a base.

Step 2: The enolate formed attacks on Methyl Iodide, as Iodide being greater in size is a good leaving group and alpha methyl moiety is generated.
Step 3: This step is acid catalyzed Bromination. Bromine is added at alpha position.
Step 4: This is elimination reaction and is according to <span>Hofmann's Rule. Here less substituted alkene is generated.</span>
