Explanation:
The structures of the starting materials 2‑methylhept‑3‑yne can be seen in the diagram attached below. We will also notice the role of NaNH₂ which acts as a strong base and whose function is to extract acidic proton and form an alkyne as a product.
The reaction with NaNH₂ yields acetylide ion which is then reacted with a straight-chain alkyl halide to form an extended carbon chain.
CHECK THE DIAGRAM BELOW.
Farmers use the property of density of cranberries to harvest the crop because an object with a density less than, in this case, water, it will float.
When farmers flood cranberry bogs with water, they know that cranberries have a density less than about 1 g/mL. Because of this, cranberries will float to the top of water and can be easily harvested.
