1. How many monochlorinated compounds of molecular formula C3 H7 Cl can be made by chlorinating propane?

To determine the number of monochlorinated compounds that can be made by chlorinating propane (C3H8), we need to consider the possible substitution sites for chlorine.

Propane (C3H8) is an alkane with three carbon atoms. Each carbon atom can potentially react with chlorine to form a monochlorinated compound.

To calculate the number of possible monochlorinated compounds, we use the formula 2^n, where n is the number of carbon atoms in the propane molecule. In this case, n = 3.

So, the number of monochlorinated compounds that can be made by chlorinating propane is 2^3, which equals 8.

Therefore, there can be a total of 8 monochlorinated compounds of the molecular formula C3H7Cl that can be made by chlorinating propane.
