That’s a hard one, but honestly i would go with a.
Answer:
See explanation below
Explanation:
You are not providing the starting material, however, I manage to find a similar question to this, so I'm gonna use it as a basis to help you answer yours.
Now let's analyze what is happening in the reaction so we can predict the final product.
We have a ketone here, reacting at first with LDA. This is a very strong base that is commonly used in reactions with ketones and aldehydes to promove a condensation. To do this, as LDA is a strong base it will occur firts an acid base reaction, substracting the most acidic hydrogen in the molecule (Which in this case, is the Beta hydrogen of the carbonile). This will cause an enolate formation.
Then, this enolate will react with the CH3I and form a new product. The final result would be a ketone with a methyl group now attached. In the picture 2, you have the mechanism and final product.

The answer is <span>C. those with the same color</span>
It would be 12000 = 1.2 * 10^4
Here is your answer:
Remember that potential energy is the energy a object has when it's NOT moving, and kinetic energy is when a object has energy when it IS moving. So examples of this kid of transformation would be kicking a soccer ball at first the soccer ball has potential energy because it's not moving but it has potential to move then when someone kicks the soccer ball it has kinetic energy because the ball is not moving.
Example one: when the video first begin "the ball had potential energy and when the ball swung and hit it that potential energy turned into kinetic energy."
Example two: As the video moves on and the two pillars crashed down it caused another ball to move, at first the "ball had potential energy because it was not moving then when the ramp went down it caused the ball to gain kinetic energy."
Example three: At the end of the video the ball push down a row of wooden blocks then lead to it hitting a "bowling ball across the finish line even though the ball moved slowly and not far it still came from potential energy into kinetic energy."
Hope this helps!
