For identifying hybrid orbitals, would this be where you would write for example: sigma(C2sp3)?

Practice problem
I’m not sure how to go about this problem, I know the answer is n=5 but I’m still struggling on how to get there. In a hydrogen atom, an electron transitions to the second quantum level from another quantum level and caused a photon with a frequency of 6.91 x 10^14 Hz to be emitted. What was the ini...

Sixth Edition 12.51
How would we be able to determine which acid is the strongest? Would we have to use periodic trends for this?
For example, between HCl and HF, which would be the stronger acid and why?

Re: How to identify Acids/Bases
If you are given a compound, identify the compound that loses an H+. For example, if in the reaction h3o+ becomes h2o, then you know that it lost a H+, or donated that. that compound will be an acid. Thank you, but how would I identify which compound would be the one that loses or gains an H+ I gue...

Just to clarify, when there is a double bond one of the bonds is a pi bond and the other is sigma bond correct? Also, when drawing this, would we draw intersecting pi bonds on the molecule?

Re: ClO2+
its molecular shape is trigonal planar because there are two atoms attached to the central atom, but the electron pair arrangement would be bent since there are two lone pairs and therefore the atoms are repulsed from the lone pairs creating a bent shape

For example, for problem 4.13 it states to give the molecular shape whereas 4.15 states to give the shape, is there a difference between the two? Would molecular shape exclude lone pairs and shape doesn't?
