See explaination
Explanation:
methyl-3-nitrobenzoate = 3-NO2-C6H4-COOCH3
Singlet at 4 ppm = CH3 from ester (COOCH3)
Triplet at 7.6 ppm = Aromatic, H5 proton
Doublet at 8.2 ppm - Aromatic, H4 and H6 protons
Singlet at 8.8 ppm - Aromatic, H2 proton
See attached file for diagrammatic representation and further solution.
The true statement will be "oxetanes are <u>five-membered ring</u><u> </u><u>ethers."</u>
The four-membered ring of octane, a saturated organic heteromonocyclic parent, contains three carbon atoms but one oxygen atom. It belongs to the family of oxetanes well and has a saturated organic heteromonocyclic parent.
Oxetanes can also be widely employed as monomers inside the cationic or anionic synthesis including both branched but also linear poly-ethers. Thermal decomposition, photolysis, as well as cycloaddition are further beneficial reactions.
The structure of oxetanes are shown as:
The Patern-Büchi reaction is another process that could result in the formation of an oxetane ring. In addition to decarboxylation of such a six-membered cyclic carbonate, diol cyclization can also create the oxetane ring.
a)Oxiranes has two carbon ring with one oxygen.
b) Oxetanes has 3 carbon ring with one oxygen
c) Dioxanes has six membered ring with two oxygen.
Therefore, the true statement will be "oxetanes are five-membered ring ethers."
Hence, the correct answer will be option (b)
