@Stuti Do the vacant 3d-orbitals of Sulphur not delocalize the negative charge? I understand that the extent of delocalization would be less.

I can't see why there is no resonance in the compound with two sulphurs

Q: Find the order of acidic strength

Aditya DevArrange the following in decreasing order of acidity I think it's S>P>R>Q (Q) forms an anti aromatic conjugate base. So its the least acidic compound here. (R) forms forms a conjugate base which is only stabilized by electron withdrawing (inductive) effect of $\ce{S}$. (P) forms an aromatic...

I have been trying this and getting it wrong for quite some time

Then I would choose balls of 2 different colours such that one of them is green and the total sum is 11?
May 3, 2023 03:49
How should I do this? There would be 3 cases (2, 3, 4, 8), (2,3,5,7) and (2, 4, 5, 6) of 1/3 probability each? These arent ordered pairs btw. Just the number of balls of different colours with highest being green

Bag contains 17 balls of 4 different colours. There exists minimum of 2 balls of a particular colour in the bag. Bag contains maximum number of green balls and the number of balls of any two colours aren't the same. If we randomly pick 11 balls from the bag such that there should be at least two balls of the same colour and the remaining balls of another colour. Then the probability of having at least one green ball among those 11 balls picked from the bag?

@TedShifrin I think "best suitable" tries to imply that one should attempt to make it least crowded crowded for the pigeons but indeed the language confusing

There are 5 holes on a wall and a total of 17 pigeons have to be kept in them. Which of the following options(choices) are correct and can be the best suitable arrangement?
a) Every filled/occupied hole has a minimum of 3 pigeons
b) Every filled /occupied hole has at least 2 pigeons but not
more than 4 pigeons
c) Every filled/occupied hole has not less than 2 pigeons
d) All of the above
e) The filled/occupied holes have not less than 4 pigeons

The answer key says it's the second option (b) but I really cant wrap my head around why the first option (a) is wrong

Hi @JohnRennie !

Can you help me out with this theoretical doubt?

Hello @JohnRennie sir. I had posted this question which I couldn't understand completely even after getting an answer. Can you please take a look at it? (The comments at the end of the recieved answer help to understand my issue better). Here's the link: physics.stackexchange.com/questions/666052/…
