d strongest acid? ob.Tenormin, a member of the gr blood pressure and improve survival after a using a calculator. educe itsprove survuup of drugs known as beta-blockers, is used to treat high workload Whival after a heart attack. It works by slowing down the ch atom in Tenormin is the most basic? OCH CHCH2NHCH(CH3)2 OH Tenormin atenolol 67.From which of the following compounds can HO-remov favors product formation? e a proton in a reaction that CH 3 COOH CH 3 CH 2 NH 2 CH 3 CH 2 N+ H3 CH 3 C CH A BCD 69.You are planning to carry out a reaction that produces protons. The reaction will be uffered at pH = 10.5. would it be better to use a protonated methylamine/methylamine buffer or a protonated ethylamine/ethylamine buffer?
