A student dried a wet crucible with a kimwipe. A piece of kimwipe was left clinging to the inside wall of the crucible. The student did not see the piece of kimwipe when adding the N a H C O 3 − K C l mixture to the crucible. The crucible and its contents were weighed and subjected to three heating cooling cycles. Could this experimental error significantly affect the percentage of N a H C O 3 in the mixture? Justify your answer with an explanation.

b. is the answer hoped i        

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.
