it does not have the same conductivity, but i want to know why they dont have the same
yes
because
be cause muta rotation is not present in ssucrose
pKa of methanol is 15.5 see this pdf for more information about pka-values: http://chemweb.unp.ac.za/chemistry/Physical_Data/pKa_compilation.pdf
Yes, the higher the conductivity concentration the higher the conductivity value in the material. Some times the conductive particles are surrounded with insulating materials which cut the conductive paths between the electrodes and as a result it stops the increase in the conductivity values to a certain limit according to the structure (texture) in the material.
ALL metals DO conduct electricity. The best conductors are gold, platinum, mercury and copper. The poorest conductor is probably lead. You can find their conductivity values from standard tables. Also don't forget that electrical conductivity is not the same a thermal(heat) conductivity.

The lower heating value of Methanol is between 643 and 652 Kjoule/mole, calculated for open combustion (GREET 1.8) or human energy expenditure (Weir, corrected for nitrogen). The higher heating value, including heat in watervapor produced, is found in tables to be between 726 and 733 KJoule/mole. Different sources give slightly different values.

The order of increasing RF values in TLC is Benzil, methanol anthracene and tryphenyl.
Outermost orbital shell of a metal has very few electrons with corresponding values of energy. This specific property accounts for the unusual electrical conductivity of metals. Highest conductivity occurs in metals with only one valence electron.

anything above 50ps/M is acceptable and usuualy values range from 150pS/M to 1500 pS/M
insulating materials have low thermal/electrical conductivity values and hence can be used in applications where resistance to heat or resistance to the passage of electrical current is required.
A comparison of the Thermal Conductivity of several common metals (higher values indicates better heat conductivity) is shown below. Silvers is best but cost makes copper a pretty good choice:Metal: Conductivity* Steel: 50 * Brass: 109 * Aluminum: 250 * Gold: 310 * Copper: 401 * Silver: 429

A typical aqueous solution containing phenolpthalein is colorless within the pH range 2 - 6.
