im trying to follow she lia's ideas of studying organic chem..but end up giving up..lolx..de mind map i created was somehow de same as de notes..den juz feel tt im wasting my time..so stopped doing le..wahahax... den i decided to understand each set of de organic notes..gimming myself more time to understand rather than juz memoin blindli..sort of work?at least i noe de wat phenol react with n wat it doesnt..hahaha...for u guys hu r mugging for chem now or lata nxt wk here r some tips for u all..
phenol can onli form ester with RCHOCl
alcohol can form ester with carboxylic acid or acyl chloride..regardless whether de R group is aromatic or wat...but for by using carboxylic acid to form esters conc sulphuric acid is needed
using RCHOCl to form ester..aromatic chloride nd NaOH whereas aliphalic chloride nd pyridine as solvent..juz rember tt alipahlic chloride will hydrolyse to form HCl...rember de tut qn?
for arenes all 3' directing substituent r deactivating groups except halogens lorh..de other deactivating groups hab a partial or fulli postive charge directly bonded to de benzene ring..e.g. C6H5NO2..de N bonded to de benzene ring is partialli positive.
halogens n electron donating group r 2,4 directing
lolx...lazi to list out all~~~booohooo still got so mani hw to do!gone*...
