Question

Why is pyridine a better base than pyrrole? The pyridine lone pair is conjugated with the aromatic system The pyrrole lone pair is conjugated with the aromatic system Two pyrrole molecules hydrogen bond with each other Pyridine has a higher molecular weight Which of these causes the frequency of bond vibration to increase Increasing bond order Changing to a heavier isotope in the bond Conjugating the bond Increasing bond polarity What will be the dominant fragmentation for 2-methylbutane Loss of a methyl radical to leave behind (CH3)2CHCH2+ Loss of a methyl radical to leave behind CH3CH+CH2CH3 Loss of an ethyl radical to leave behind (CH3)2CH+ Loss of a hydrogen radical to leave behind (CH3)2C+CH2CH3 Loss of an isopropyl radical to leave behind +CH2CH3
