Answer:
See explanation below
Explanation:
In this case we have the starting reactant which is the ethine, In the first step reacts with NaNH₂, a strong base. This base will substract the hydrogen from one of the carbon of the ethine, and form a carbanion. This will react with the propane bromide, displacing the bromine and forming a 5 carbon chain with the triple bond on the carbon 1 and 2.
In the second step, reacts with the lindlar catalyst to do a reduction, and form a double bond between carbon 1 and 2. In essence, compound A is similar to compound B.
Finally B reacts with water in acid and makes a addition reaction, and form an alcohol.
The whole process can be seen in the picture below.

At the top of the swing is your answer.
Kinetic energy increases as an object falls. Increase of speed also increases kinetic energy. The kinetic energy is at zero when an object is not moving
Answer:
Blue
Explanation:
Blue would have the longest wave length because following ROY G BIV the wave length distance between the two decreases as you move from Red to Violet.
[A] 0
When opposing forces act on an object, this means that the object isn't moving at all. This is also known as a "balanced force." If the forces of the same and you add them together the answer is 0.
