HELP’nQuestion 3. Can you please explain how to get the answer? Starting with acetylene, devise a scheme to prepare 1-chloroheptanol . There is more
than one way to complete this synthesis. It can be completed in as few as three reactions. You
can use any alkyl halides as needed as sources of carbon atoms.

See explanation and image attached

Explanation:

Let us consider the mechanism attached to this answer. This is only one of the ways of synthesizing the required product.

The starting material is acetylene. This is reacted with sodamide in ammonia alongside methyl iodide. The process is repeated again, this time using butyl iodide. The alkyne is now reduced using hydrogen.

The alkane formed may now be chlorinated in the presence of light using the chlorine molecule. A mixture of alkyl halides are obtained.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
