4. Assuming ideal solution conditions, calculate the solubility of p-dibromobenzene in benzene at (a) 15°C and (b) 30°C. The standard melting point of p-dibromobenzene is 87.0°C and its enthalpy of fusion is equal to 13.2 kJ/mol. (8 pts)
Can
you please tell me if these are ortho, meta, or para?

Considering 1H-NMR analysis of
substituted benzenes (for ortho, para, meta nitrobromobenzene and
ortho, para dinitro bromobenzene, or meta para dinitrobromobenzene)
: What is the splitting patterns for ring hydrogens for the
substituted benzenes? Using ??3-bond and 4-bond J coupling
constants, what are: ??Relative chemical shifts of ring
hydrogens?
which of the following substituents will stabilize the charge on the carboxylic acid on the benzene ring created during hydrolysis. And why? 1. methyl group at the para postion to the carboxylic group on the benzene ring 2. methyl group at the meta position to the carboxylic acid group on the benzene ring 3. methoxy group at the meta position to the carboxylic acid group on the benene ring 4. methoxy group at the para position to the carboxylic acid...
Classify each substituent as ortho, para activators; ortho, para deactivators; or meta deactivators. ortho, para activators ortho, para deactivators meta deactivators CHO COon NH2 C(CH3)a
3. Classify the following substituents as orthol para activating, ortho/para deactivating meta deactivating. CN F
i know that C is a meta director, but are any of these ortho
or para, or any other kind of directors? thanks!
4. Which of the following is a meta director?
