Identify the substrate: 3-bromo-3-methyl-1-butene is a tertiary alkyl halide, which is prone to elimination reactions. Recognize the base: CH3O− (methoxide ion) is a strong base, favoring E2 elimination reactions. View full solution ...
verapamil is a lipophilic weak base with a protonated tertiary amine group at neutral pH. At a pH of almost 10 verapamil exists in its least ionized state, so that it has a high affinity to neutral lipid bilayers. At a neutral pH and in particular at a pathophysiologically relevant slightly...
Romania, it is a teaching university hospital and a tertiary referral center for acute poisoning, and therefore it could be used as a representative institution in this region. Another limitation was that the CBC-based parameters were analyzed only at the time of the patients' presentation and ...
