The molecular interaction responsible for hydrogen bonding in HF.

In nylon, intermolecular forces of attraction are hydrogen bonding / dipole interactions.

Which of the following property will be more in case of molecule having inter molecular hydrogen bonding in comparison to other isomeric molecule having intra-molecular H-bonding:

Statement-1 : Dipole-dipole interaction is only non covalent force of interaction for hydrogen bonding. Statement-2 : F is the most electronegative element and HF has symmetrical hydrogen bonding. (1) Statement-1 and Statement-2 are true and Statement-2 is correct explanation of Statemnt-1. (2) Statement-1 and Statement-2 are true but Statement-2 is not correct explanation of Statement-1. (3) Statement-1 is true and Statement-2 is false. (4)Statement-1 is false and Statement-2 is false.

In nylon intermolecular forces of attraction are hydrogen bonding/dipole-dipole interactions.

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Dipole-dipole interactions are the only non-covalent interactions, resulting in hydrogen bond formation. Reason R : Fluorine is the most electronegative element and hydrogen bonds in HF are symmetrical. In the light of the above statements, choose the most appropriate answer from the options given below.
