Thank you sir, I need one clarification sir, as the c=c stretching frequency increase with the size of the ring decreases.?

[@drgajapathyschemistryclass4773]

Absorption frequency decreases as the internal angle decreases until it reaches a minimum at 90 deg in cyclobutane.The frequency increases again for cyclopropene becaus e the vibration is coupled with C-C single bond vibration.
