Pure (S)-2-butanol has a specific rotation of +13.52 degrees. A sample of 2-butanol prepared in the lab and purified by distillation has a calculated specific rotation of +6.76 degrees. What can you conclude about the composition ?

A

50% (S), 50% impurity

B

50% (S), 50% (R)

C

50% (S), 50% racemic

D

some other mixture

Text Solution

Verified by Experts

The correct Answer is:
C
Optical purity = `("Optical rotation of mixture")/("Optical rotation of pure compound") xx 100 , O.P. = (6.76)/(13.52) xx 100`

Given below are observations on molar specific heats at room temperature of some common gases. {:("Gas","Molar specific heat "(C_(v))),(,("cal mol"^(1)K^(-1))),("Hydrogen",4.87),("Nitrogen",4.97),("Oxygen",5.02),("Nitric oxide",4.99),("Carbon monoxide",5.01),("Chlorine",6.17):} The measured molar specific heats of these gases are markedly different from those for monatomic gases. Typically, molar specific heat of a monatomie gas is 2.52 cal/mol K. Explain this difference. What can you infer from the somewhat larger than the rest) value for chlorine ?

For a general reaction given below, the value of solubility product can be given us {:(A_(x)B_(y),=xA^(+y),+yB^(-x)),(a,0,0),(a-s,xs,ys):} K_(sp)=(xs)^(x).(ys)^(y) (or) K_(sp)=x^(x)y^(y) (S)^(x+y) Solubility product gives us not only an idea about the solubility of an electrolyte in a solvent but also helps in explaining concept of precipitation and calculation [H^(+)] ion, [OH^(-) ] ion. It is also useful in qualitative analysis for the idetification and separation of basic radicals What is the molar solubility of Cu(OH)_(2) , in 1.0 M NH_(3) if the deep blue complex ion [Cu(NH_(3))_(4)]^(2+) is formed.
