How many grams of Sodium hydroxide would you need to make 1L of  a 2M solution ?

(H3O+) = 1.9x10%-3

One stereoisomer of 1,4 dibromocyclohexane has a melting point of 113 oC, the other isomer melts below 0 oC. Draw both structure and assign melting points to the structures. Justify your choice

Cyclopentaethiol has a markedly lower melting point than cyclopentanol even though, it has a higher molecular weight. Explain

The combustion of heptane C7H16 in a constant volume calorimeter

gave the value of Qv = -4793 KJ at 25̊C. What will be their enthalpy

change of the process at 25̊C? [C7H16 (l) + 11O2 (g) = 7CO2 (g) +

8H2O (l).]

The most stable conformation of butane is anti conformation and it's least stable conformation is eclipsed conformation. Why?
