Question

When absorption energy is increased, then the shift is called ______.

• A. Hypochromic shift
• B. Hyperchromic shift
• C. Bathochromic shift
• D. Hypsochromic shift

Hint:

Hypsochromic = higher energy = shorter wavelength (blue shift).

Answer 1

The Correct Option is D

A hypsochromic shift, also known as a blue shift, occurs when the absorption maximum shifts to a shorter wavelength (higher energy). This typically happens due to changes in the electronic environment or solvent polarity.
