Identify whether the given statements are true or false.
Statement-I: An H-bond in case of HF molecule, alcohol or water molecules is an intermolecular hydrogen bond.
Statement-II: There is an intramolecular hydrogen bonding in an o-nitrophenol molecule.
-
A.
Statement-I is true but Statement-II is false.
-
B.
Both the statements are true.
-
C.
Statement-I is false but Statement-II is true.
-
D.
Both the statements are false.
Correct Answer:
B. Both the statements are true.
Explanation:
Both statements are accurate regarding chemical bonding. Statement I is true because hydrogen bonding between separate molecules of HF, alcohol, or water is classified as intermolecular, which significantly influences their physical properties like boiling points. Statement II is also true as o-nitrophenol contains a hydroxyl group and a nitro group in close proximity on the same benzene ring, allowing a hydrogen bond to form within the single molecule, a process known as intramolecular hydrogen bonding. This internal bond results in o-nitrophenol being more volatile compared to its para-isomer. Therefore, since both statements are correct, the answer is that both statements are true.
