comment Electronic configuration of the actinides
Thank you for answering! I wonder, since energies of orbitals of elements beyond hydrogen can't be found (as mentioned in the comments of your first link), are the comments in the book on the increasing and decreasing energies of 5f orbitals compared to 6d just conjectures based on the electronic configuration determined by spectroscopy?

comment The major product of the following reaction
Hey, all of your compounds except the first one are wrong as they have 5 carbons.

comment Nucleophilic addition - Propanal vs Benzaldehyde
@SoumikDas Sorry, I got muddled while typing the last comment. I meant more nucleophilic for the example of phenol. Referring to the second part of your comment, in my example, the carbon of the carbonyl doesn't get any decrease in $\delta +$ or increase in $\delta -$ in the resonance hybrid, so it's electrophilicity shouldn't decrease? Or is the increase in $\delta -$ because the carbon is sp2 hybridised in resonating structures, causing it to become more electronegative? I have understood the logic in terms of shift in $\pi$ electron cloud

comment Nucleophilic addition - Propanal vs Benzaldehyde
@SoumikDas Oh I got it. I didn't know I was supposed to think in terms of $\pi$ electron cloud shift. Btw, is there a way to justify this decrease in electrophilicity just the way increase in electrophilicity in say, phenol, is justified (the lone pair of electrons of oxygen are delocalised in the ortho and para positions, making those positions more electrophilic)?

comment Nucleophilic addition - Propanal vs Benzaldehyde
@SoumikDas Okay, but doesn't the carbon attached to the carbonyl get a positive charge in the last resonating structure? So, its electrophilicity should increase? Honestly, I don't exactly understand how resonating structures affect electrophilicity or nucleophilicity, so should I change my question to that?

@Zhe Thanks a lot for your help. Hopefully, someone who can access it will see this question :)

comment Mechanism of the Gatterman Reaction
@Zhe Hey, I just found this - onlinelibrary.wiley.com/doi/pdf/10.1002/9780470638859.conrr2‌​65 while I was googling the reaction. Unfortunately, I can't access these papers. If you can, would you check if it talks about any mechanism? Thanks
