Answer 2

Answer: Methyl nitrite or nitro methane will form along with potassium chloride.

Explanation:

When the primary halo alkanes are treated with potassium nitrite results in formation of nitro alkanes.

$R-X+KNO_2(or NaNO_2)\rightarrow R-NO_2+KX(or NaX)$

When the methyl chloride is treated with potassium nitrite is give methane will form along with potassium chloride as a product.
