Answer to Question #314206 in Organic Chemistry for nur

Question

P, Q and R is An intermediate in the production of commodities such as herbicides, dyestuffs and rubber(C7H7Cl)

a) what is molecular structure of C7H7Cl

b)Regardless of compound P, Q and R; which pair of the molecules are isomeric and give a reason.

c)Give the possibility of structure P, Q and R with a correct nomenclature.

Answer 1

a)C₆H₅CH₂Cl

b) Isomers that differ in connectivity are called constitutional (sometimes structural) isomers. They have the same parts, but those parts are attached to each other differently. The bracelets of red and green beads mentioned above are analogous to constitutional isomers. The simplest hydrocarbons—methane (CH₄), ethane (CH₃CH₃), and propane (CH₃CH₂CH₃)—have no constitutional isomers, as there is no other way to connect the carbons and hydrogens of these molecules consistent with the tetravalency of carbon and the univalency of hydrogen.

c)

Q & S are not resonating structures

R & S are resonating structures

P & R are tautomers

P & Q are resonating structures
