arenes and phenol and acyl chloride

Question 1

what are the propreties of benzene ?

Answer 1

1) all bond angles and length are equvialent
2) benzene is a symmetrical molecule
3) benzene is a basic frame work of sigma bond
4) benzene is hybrid between sigma and pi bond

Question 2

why phenol is more readily then nitro benzene?

Answer 2

phenol is faster because it contains (OH) group that is electron donating group increase the electron charge density around benzene and makes it more reactive

Question 3

why nitrobenzene is slower than phenol?

Answer 3

because it contains No2 group that is electron withdrawing group decrease the electron charge density around benzene and make it less reactive for electrophile

Question 4

why acyl chloride is more polarized then alkyl choride/ aryl chloride ?

Answer 4

acyl chloride is highly polarized due to the 2 adjacent electro -negative elements so any nucleophile can attack easily
