What properties would you expect to be different for the two enantiomers of 2-pentanol?
-BARSIC- [3]

Answer: direction of rotation of plane polarized light and reaction with chiral reagents.

Explanation:

Enantiomers are stereoisimers which are mirror images of each other. They possess the same physical and chemical properties except that the direction of rotation of plane polarized light and reaction with chiral reagents. (+)-2-pentanol will rotate plane polarized light to the right and react with dextrorotatory enantiomers of chiral reagents while (-)-2-pentanol will rotate plane polarized light to the left and react with leavorotatory enantiomers of chiral reagents.

How many molecules of oxygen are produced when a sample of 38.9 g of water is decomposed by electricity?
statuscvo [17]

Answer:

A) 6.5\times 10^{23}\ \text{molecules}

Explanation:

m = Mass of water = 38.9

M = Molar mass of water = 18 g/mol

N_A = Avogadro's number = 6.022\times 10^{23}\ \text{mol}^{-1}

The reaction of electrolysis would be

2H_2O(l)\rightarrow 2H_2(g)+O_2(g)

Number of moles of H_2O

n=\dfrac{m}{M}\\\Rightarrow n=\dfrac{38.9}{18}\ \text{mol}

From the reaction it can be seen that 2 moles of H_2O gives 1 mole of O_2

So, number of moles of O_2 produced is

\dfrac{38.9}{18}\times \dfrac{1}{2}=1.081\ \text{mol}

Number of molecules

1.081N_A=1.081\times 6.022\times 10^{23}\\ =6.5\times 10^{23}

So, 6.5\times 10^{23}\ \text{molecules} of oxygen is produced.
