The molecule expand to relieve steric strain before undergoing torsion to a non-planar structure in order to have several resonating structures.
<h3>What is a molecule?</h3>
It should be noted that a molecule simply mean the group of atoms that are bonded together that represents the smallest fundamental unit if the chemical compound.
It should be noted that structures containing fused benzene rings have extensive conjugation. Due to this, they can undergo resonance.
This is vital in decreasing the overall energy of the molecule and helps increase its stability. When there's a change in torsion angle to relieve the steric strain, the molecule won't be planar, hence, the energy will increase and the stability will reduce.

Ok. I finally understood that you need to complete (fill in the blank) the last sentence: The weight of a space probe on the surface of Mars is about ______________
The answer is one third its weight on the surface of Earth.
You can find that by using the formula for the weight:
weight = mass * acceleration due to gravity
So, given that the mass is constant and the acceleration due to gravity is one third, the weight is also one third.
Answer:2p→1s
Explanation:
Frequency is inversely proportional to wavelength. The higher the frequency, the shorter that wavelength. The smaller the frequency the longer the wavelength. The frequency of light associated with 2p→1s is less than the frequency of light associated with 3p→1s since the latter represents transition from a much higher energy level. It follows that the wavelength associated with the former will be longer since its frequency is lesser. This deduction follows from our argument about the inverse relationship between frequency and wavelength.
