When treated with HCI, only pyridine forms a hydrochloride salt, whereas pyrrole is unreactive Which of the following is not a valid explanation for this observed reactivity? pyridine ругrole O The lone pair on pyridine is not part of the aromatic system. O The lone pair on pyridine can be protonated without disrupting the aromatic stability. O The lone pair on pyrrole is sp hybridized and is less prone to protonation. O Protonation of pyrrole leads to a nonaromatic cation, which is less stable O The lone pair on pyrrole is involved in making the compound aromatic and thus is less susceptible to protonation.arrow_forwardThe order of increasing acidity is Phenol < meta-cyanophenol < ortho-cyanophenol 1.how about para-cyanophenol??does it has higher acidicity than both ortho-cyanophenol and meta cyanophenol or lower?? 2.why does ortho-cyanophenol have higher acidicity than meta cyanophenol?? 3. why doesmeta cyanophenol have higher acidicity than Phenolarrow_forward
