Which protons will have the highest chemical shift (which protons will be least shielded from the applied magnetic field) in the 1H NMR spectrum of 1-pentanol?

Butterfly wingspan is 7.7

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

If this is a true or galse then its true but if not then what is the question?
