(a) Interpretation: The number of inches by which a meter stick is longer than a yardstick is to be calculated. Concept introduction: The metric system unit is the unit system which is accepted as the standard system of unit internationally. Thenonmetric units are the common unit system which is not standard for the parameter to be calculated.

Part II. Given two isomers: 2-methylpentane (A) and 2,2-dimethyl butane (B) answer the following:
(a) match structures of isomers given their mass spectra below (spectra A and spectra B)
(b) Draw the fragments given the following prominent peaks from
each spectrum:
Spectra A m/2 =43 and 1/2-57
spectra B m/2 = 43
(c) why is 1/2=57 peak in spectrum A more intense compared
to the same peak in spectrum B.
