For each conjugate acid-base pair, identify the first species as an acid or a base and the second species as its conjugate acid or conjugate base. In addition, draw Lewis structures for each species, showing all valence electrons and any formal charges. • Draw all atoms, including hydrogen atoms. Apply formal charges where appropriate. Assign lone pairs and radical electrons where appropriate. (a) CH₂ CH₂ CH₂OH, CH₂CH₂CH₂O (1) CH₂CH₂CH₂OH is the CH₂CH₂CH₂O is the [ (ii) Draw the Lewis structure of CH, CH₂ CH₂OH. and

I find it pretty hard to understand the difference in boiling points when just given the shape of the molecule. Please help!

Why the extended pi(π) conjugated are not suitable phosphorescence properties?  Please answer shorty at your own words. Answer should be to the point.

When are isosbestic points observed and why?

Q.3 The elevation of boiling point and depression of freezing point of a certain solution of a monobasic acid HA in benzene are AT, and AT, respectively. HA exists usually as a monomer, but it dissociates into ions (with degree of dissociation a) at the boiling point T, of the solution, whereas at the freezing point T, of the solution, HA exists as (HA)n with a fixed value of n. The molal boiling point elevation constant and molal freezing point depression constant are K, and Kf, respectively. The correct expression for n is Ans X 1. n = [AT; K; (1+a)] / (AT, K, ) 2. n = [AT, K, (1+a)] / (AT; K; ) 3. n = (AT, K; ) / [AT, K, (1+a)) X 4. n = (AT, K, )/ [AT; K, (1+a)] %3D
