What was the theoretical yield of a reaction if 50g are formed with a 10% yield? A: 200g
B: 100g
C: 250g
D: 500g

500g

Explanation:

We are asked to find the theoretical yield of a reaction, and we are given the following information:

In order to find the the theoretical yield we must use the following formula:

We have to convert the percents to real numbers before the calculations.  We can do it dividing the percent value into 100, so:

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
