317261 Resonance in most of organic molecules

1 Increases stability
2 Decreases stability
3 Increases reactivity
4 Increases energy
CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317262 Given below are two statements: one is labelled as assertion and other is labelled as reason.
Assertion :
There is evidence for existence of N -methylacetamide in two structural froms I and II as shown below:
supporting img
Reason :
Rotation about carbon-nitrogen bond is restricted due to resonance.
In the light of the above statements, choose the correct option from the following:

1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Assertion is false but Reason is true.
