Compound x and compound y are constitutional isomers with the molecular formula c5h10. compound x possesses a carbon-carbon double bond in the trans configuration, while compound y possesses a carbon-carbon double bond that is not stereoisomeric: get answering molecular drawing questions get answering molecular drawing questions. draw the structure of compound x.

Explanation:

You can start by drawing molecules taking into account the following factors:

Then the initial molecule should be ethylene, and we have 3 missing carbons, 2 of them would let us follow the 3rd rule and we have the 2-Butene and we are missing 1 carbon, that atom cannot be as a substituent of any carbon forming the double bond because there wouldnt be any stereoisomers, then it should be connected with a substituent carbon giving us the 2-Pentene

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.
